We tant spatial component. It hence seems natural to incorporate this introduce geo word clouds: word clouds which capture not only the spatial component when creating word clouds. Consequently there are many (manually crafted) examples of “word cloud maps”, that frequency but also the spatial relevance of words. 1 Our input is a set of locations from one (or more) geographic re- is, geographic maps which are composed solely of words (often gions with (possibly several) text labels per location.

Furthermore, they “draw” the geographic regions, from the location of labels, their relative sizes and the number of spatial which the input is taken, to both attract attention and to give visual clusters. The resulting word clouds are visually
