Overview first Tools 2. Zoom and filter 3. Then details-on-demand Effective Visualization 7 Business Usecases for Data Visualization The probable primary usecases for the data visualization include 1. Navigation Flow a. Code Flow b. Data Lineage, how data could run through a system of different ETL (extract - transform - load) components. 2. Process flow 8 Business Usecases for Data Visualization • To visualize - Dependency of more than 1000+ different packages and how they interact with eachother Eg: Dagre Layout - Process flows like how a user runs through different forms in an application Eg: CoSE (Compund Spring Embedder) Layouts - How data flows through different ETL(Extract Transform and Load) Components of the Database. Eg: Sankey Diagrams 9 Different Data Models - supported Layouts Model description Supported Graphs or Examples Layouts Network Node/link Diagram(uses link based Dagre, CoSE, cola layout algorithms) Tree / Hierarchal General tree Visualization Dendogram, treemap Temporal Visualizing Data lineage Alluvial, Sankey Arbitrary Graphs Node-Link Graphs, Matrix force directed graphs Processes Process diagrams CoSE(compound Spring Embedder) layout 10 Sankey Diagram Sankey Diagram depicts flows of any kind, where the width of each flow pictured is based on its quantity. • Sankey diagrams are very good at showing particular kinds of complex information - • Where money came from & went to (budgets, contributions) • Flows of energy from source to destination • Flows of goods from place to place • ...and potentially many more. 11 Sankey Diagram -2 The width of the arrows is proportional to the flow quantity The arrows show flows from one node to another node - ideal for production systems or for value chains, as this can not achieved using pie or bar charts. Sankey diagrams are more suitable for • visualizing energy or material flows when • compared to conventional bar or pie charts • and even flow charts. • Effective communication of messages 12 Navigation Flow FMBs calling other FMBs MMBs (menus) Libraries Unused modules (=not called, not referenced) 13 CoSE Bilkent Layout • CoSE is an algorithm based on force-directed layout scheme with extensions to handle . Multi-level nesting . Edges between nodes of arbitrary nesting level . Varying node sizes . Other possible application-specific constraints. 14 CoSE Bilkent Expanding nodes- Example 15 JavaScript Libraries: D3 and Cytoscape • D3 stands for Data Driven Documents. D3.js is a JavaScript library for manipulating documents based on data. • Cytoscape is an open source software platform for visualizing complex networks and integrating these with any type of attribute data 16 D3 Features • Data Driven • DOM Manipulation • Data Driven Elements: It authorize data to dynamically generate elements and apply styles to the elements, be it a table, a graph or any other HTML element and/or group of elements. • Dynamic Properties • Types of visualization • Custom Visualizations • Transitions • Interaction and animation 17 Cytoscape Features • Multi-graph layouts support • Interactive graph manipulation and analysis possible (CRUD) • graph theory algorithms are included, such as connectivity search, shortest path, minimum span tree, minimum cut, ranking and centrality measures. • Import graph and data via Jason & Export (PNG , PDF or JPG) Incl.

  • Go with the Flow: Sankey Diagrams Illustrate Energy Economy
    Narrative: In this EcoWest presentation, we break down energy trends in the U.S. and Western states by using a graphic known as a Sankey diagram. Energy flows through everything so it’s only fitting to use this type of flow chart to depict our complex energy economy. 1 Narrative: Sankey diagrams are named after an Irish military officer who used the graphic in 1898 in a publication on steam engines. Since then, Sankey’s diagrams have won a dedicated following among data visualization nerds. The graphics summarize flows through a system by varying the width of lines according to the magnitude of energy, water, or some other commodity. Source: Wikipedia.org URL: http://en.wikipedia.org/wiki/Matthew_Henry_Phineas_Riall_Sankey 2 Narrative: One of the earliest and most famous examples of the form illustrates Napoleon’s disastrous Russian campaign in the early 19th century. Source: Napoleon's retreat from Moscow, by Adolph Northen (1828–1876) URL: http://en.wikipedia.org/wiki/File:Napoleons_retreat_from_moscow.jp g 3 Narrative: Created by Charles Joseph Minard, a French civil engineer, the graphic depicts the army’s movement across Europe and shows how their ranks were reduced from 422,000 troops in June 1812, when they invaded Russia, to just 10,000, when the remnants of the force staggered back into Poland after retreating through a brutal winter. Data visualization guru Edward Tufte says it’s “probably the best statistical graphic ever drawn.” Source: Wikipedia.org URL: http://en.wikipedia.org/wiki/Charles_Joseph_Minard 4 Narrative: Sankey diagrams created by the Lawrence Livermore National Laboratory depict both the source and use of energy.

  • Identifying Students' Progress and Mobility Patterns in Higher
    ORAN, MARTIN, KLYMKOWSKY, STUBBS 1 Identifying Students’ Progress and Mobility Patterns in Higher Education Through Open-Source Visualization Ali Oran, Andrew Martin, Michael Klymkowsky, and Robert Stubbs Abstract For ensuring students’ continuous achievement of academic excellence, higher education institutions commonly engage in periodic and critical revision of its academic programs. Depending on the goals and the resources of the institution, these revisions can focus only on an analysis of retention-graduation rates of different entry cohorts over the years, or survey results measuring students level of satisfaction in their programs. They can also be more comprehensive requiring an analysis of the content, scope, and alignment of a program’s curricula, for improving academic excellence. The revisions require the academic units to collaborate with university’s data experts, commonly the Institutional Research Office, to gather the needed information. The information for departments’ faculty and decision makers should be presentable in a highly-informative yet easily-interpretable manner, so that the review committee can quickly notice areas of improvement and take actions afterwards. In this study, we discuss the development and practical use of a visual that was developed with these key points in mind. The visuals, referred by us as “Students’ Progress Visuals”, are based on the Sankey diagram and provide information on students’ progress and mobility patterns in an academic unit over time in an easily understandable format. They were developed using open source software, and recently began to be used by several departments of our research intensive higher-ed institution for academic units’ review processes, which includes members of the campus community and external area experts.

In this paper, open-source data on global oil trade, from 1996 to 2016, published by British Petroleum was used. It was analysed using the shapefile of the countries of the world in the open-source software like StatPlanet, R and QGIS. Visualizations were created using different maps with combinations of graphics and plots, like choropleth, dot density, graduated symbols, 3D maps, Sankey diagrams, hybrid maps, animations, etc. to depict the global petroleum trade. Certain inferences could be quickly made like, Venezuela and Iran are rapidly rising as the producers of crude oil. The strong-hold is shifting from the Gulf countries since China, Sudan and Kazakhstan have shown a high rate of positive growth in crude reserves.

  • Testing Covariance Models for MEG Source Reconstruction of Hippocampal Activity
    Testing covariance models for MEG source reconstruction of hippocampal activity Supplementary Material George C. O’Neilla, Daniel N. Barryb, Tim M. Tierneya, Stephanie Mellora, Eleanor A. Maguirea, Gareth R. Barnesa aWellcome Centre for Human Neuroimaging, UCL Queen Square Institute of Neurology, University College London, London, UK bDepartment of Experimental Psychology, University College London, London, UK 1) The pattern of hippocampal results in the MEG literature To investigate the prevalence of unilateral and bilateral hippocampal activity in reported MEG studies, we performed a miniature review of literature. Methods We searched the PubMed database for all documents that contained both the terms magnetoencephalography and hippocampus that were published between 1st Jan 1990 and 1st July 2020. We then checked that each paper returned by PubMed met the following criteria: 1. The publication was not a duplicate result of a previously parsed result; 2. The publication was not a literature review or commentary; 3. The publication was not pathological case report; 4. The publication was not a simulation study; 5. The publication contained electrophysiological recordings of humans that covered both hippocampal regions; 6. A source-level analysis of the experimental data was performed; 7. A significant activation or network node was identified in either or both hippocampal regions. If all criteria were met, we recorded whether there were reported activations in one or both hippocampal regions and identified what type of experiment was performed and what source inversion method was implemented. Results PubMed retuned 191 publications containing both keywords, of which we eliminated 108 for failing to meet all 7 criteria, leaving 83 qualifying publications.

  • A Sankey Framework for Energy and Exergy Flows1
    The 2nd ICEST, Cairo, Egypt, 18-21 February 2013 A Sankey Framework for Energy and Exergy Flows1 Kamalakannan Soundararajan a, Hiang Kwee Ho a, Bin Su a a Energy Studies Institute, National University of Singapore, Singapore Abstract Energy flow diagrams in the form of Sankey diagrams have been identified as a useful tool in energy management and performance improvement. However there is a lack of understanding on how such diagrams should be designed and developed for different applications and objectives. At the national level, matching various features of Sankey diagrams with the various objectives of energy performance management provides a framework for better understanding how Sankey diagrams can be designed for national level analysis. As part of the framework, boundaries outlined around a group of facilities provide a refined representation of sub-systems that trace energy use in various conversion devices, products and services. Such a representation identifies potential areas for energy savings; an important objective of energy performance management. However, Sankey diagrams based on energy balance falls short in effectively meeting this objective. Sankey diagrams based on exergy balance on the other hand provide unique advantages in identifying potential areas for energy savings. This is illustrated at a facility level, using the example of a LNG regasification facility that overlays both energy and exergy flow diagrams. Keywords: Sankey diagrams, national level energy analysis, energy stages, energy flows, energy savings, exergy balance 1. Introduction Sankey diagrams have been used as an effective tool to focus on energy flow and its distribution across various energy systems. It is represented by arrows, where the width of which represents the magnitude of the flow.

  • How Do Ancestral Traits Shape Family Trees Over Generations?
    Author manuscript, published in IEEE Transactions on Visualization and Computer Graphics, 24(1), pp. 205-214, 2018. DOI: 10.1109/TVCG.2017.2744080 How Do Ancestral Traits Shape Family Trees over Generations? Siwei Fu, Hao Dong, Weiwei Cui, Jian Zhao, and Huamin Qu a b c Figure 1. (a) TreeEvo organizes and demonstrates the entire collection of family trees by growth and continuity in a Sankey diagram like visualization. In this example, Sankey nodes in each row represent all trees with the same depth, which are categorized into three groups: left-inclined (blue), balanced (white), and right-inclined (red). (b) After the blue Sankey node is selected, detailed composition of the node, i.e., a set of trees, is displayed in a space-efficient layout. Trees of each specific structure are represented by a rectangle, of which the color indicates inclination and area encodes the number trees. The node-link structure of family trees is displayed if the rectangle is large enough. (c) Family trees included in the red Sankey node, which are right-inclined, are displayed upon selection. Abstract— Whether and how does the structure of family trees differ by ancestral traits over generations? This is a fundamental question regarding the structural heterogeneity of family trees for the multi-generational transmission research. However, previous work mostly focuses on parent-child scenarios due to the lack of proper tools to handle the complexity of extending the research to multi-generational processes. Through an iterative design study with social scientists and historians, we develop TreeEvo that assists users to generate and test empirical hypotheses for multi-generational research.

Sankey diagram. 14. Sliding scale. Tips and Tricks • Design data visualizations for your audience. Consider if they need a short infographic or an in-depth report. If you are unsure what your audience needs, ask them in a survey or focus group. Ask a few members of your audience to review the visualization before you finalize it. • Keep your visualizations simple by avoiding 3D graphs and too many colors. A color palette is an important tool that can be used for simplicity, branding, visibility and consistency. Additionally, you can break up complicated graphs into multiple graphs that are easy to read and interpret. • Remove unnecessary text, gridlines, pictures and icons. Do not include pictures that are irrelevant to your study findings or message. This will help you reduce clutter so readers can easily see and understand your visualization. • To help simplify visualizations and reduce clutter, use white space, which is a negative or unmarked space between charts, images, icons and texts. This space can be any color as long as the space is empty of other elements. • The internet contains a variety of data visualizations that are often disseminated through social media, which is why it is important to always credit and cite all sources.
