Abstract

Geographic visualizations, like choropleth maps, are used to visualize data on geographic regions. In this thesis a choropleth map was implemented to display quantities of publications of scientific texts and papers. With the use of a choropleth map the viewer is able to interpret how quantitative data changes on different geographic regions. The main feature that distinguishes the implemented choropleth map from conventional ones is the use of map navigation. The choropleth map can be zoomed and panned to different map regions. What makes this map navigation so special is the use of semantic zooming to allow the level of detail of the map to change on discrete zoom steps. The change of the level of detail means that administrative regions are being divided into smaller administrative regions which are than again colorized individually to create a new, more detailed, choropleth map. Other interactions with the choropleth map are introduced additionally. The other interactions with the map range from the manipulation of the map appearance to filtering the displayed data set.
