Visualizations of infrastructure

The author Thomas Kräftner uses [several datasets](http://data.wien.gv.at/katalog/) of Open Government Data to investigate questions about the ideal location from certain points of view with his visualizations of the infrastructure of the city of Vienna. For an ambitious hobby swimmer, for example, the nearest swimming area or bathing area should never be far away. The visualizations of the perimeter distances make the infrastructure offer of the city recognizable under a certain aspect at a glance. The author explicitly refers to the visualizations as "first thoughts" and asks for feedback on the previous considerations for further development. The visualizations are available as graphics.
