In the spring 2012, Johan Björn and Raimo Muurinen, the guys of Avanto Insight Oy, asked several companies to write an open source geographical and interactive data visualization for Pirkanmaan Liitto. I won the bid and got to work. The app turned out nice and it was hosted on the website of Pirkanmaan Liitto for a couple of years.
The image above is my original UI design plan and the image below represents the finished application. The app displays statistics for ten topics and each topic has multiple year ranges for citizens to explore.
The open source code is available at github.com/avantoinsight/visu
