Summary of the paper: jonasoesch.ch/articles/the... 1/3

Two smartphones displaying alternative thematic world maps.
The left screen shows a split-continent map with countries grouped and resized by region (e.g., Europe, Africa, Asia) using color to indicate data levels (legend: Hoch, Mittel, Tief, Sehr tief). Smaller countries like Rwanda and Panama are clearly labeled and more visible due to the rearranged layout.
The right screen displays a bubble map, where countries are represented by circles scaled to population size and shaded by data intensity. Larger countries like China and the U.S. have prominent bubbles, while smaller countries remain visible. Labels indicate population figures for Switzerland and China.
