Two-dimensional input panels

Two input parameters can be specified simultaneously by moving a dot over a rectangular area. This is shown in the example below. The body mass index (BMI) is derived from the height and weight of a person. The height and weight are adjusted by dragging the pink dot. For example, a height of 175cm and a weight of 75kg shows a BMI of 23.4.

Glitter colours

The map of Berlin shows each district in another glitter colour. The glitter colours reflect the results of the 2016 election of the Berlin parliament (Abgeordnetenhaus). The political parties are presented by the officially assigned colours. The fraction of pixels in a certain district reflects the fraction of votes for the respective political party (here the Erststimme). For example, the many eye-catching green dots in the middle of the map are related to the high number of votes for the candidate of the∏ green party (Grüne) in Friedrichshain-Kreuzberg.
