[OSM-talk] History flow visualizations of contributions over time

[Eric Marsden]

Hi,

I have been experimenting with rendering history flow visualizations of
Openstreetmap contributors for a region. These charts show the most
prolific contributors in the region and how their contribution volume
changed over time.

Some sample visualizations for Paris, London, Berlin, Wien, Toulouse,
Lyon together with source code to generate your own are available at
