Data visualisation meets children’s curiosity. I immersed myself in geoinformatics to find out how postal services in the USA, in Germany and in Hungary carved their countries into mosaics of postal code areas. Visually striking maps emerge from the opaque depths of numerical data. Do enjoy and please share.

OpenStreetMap provided me with the data for Germany and Hungary. What a resource! I learnt a lot about querying the database. Many thanks to the designers, programmers, contributors!
