A May 15-17 weekend of cold weather turning hot in Switzerland. The graph shows wind speed and direction, with different colours for each of the almost 100 SwissMetNet weather stations, whose data was published on the Swiss pilot Open Government Data portal, collected using a community-built API, and visualised using D3, SVG and Inkscape.

The code can be tested here:

Thanks to Marcel Stoer for the open data SMN API which was used to collect the data using this simple curl script:

watch -n 600 'curl > smn_`date +"%Y-%m-%d_%H-%M"`.json'

With thanks to Daniela Nowak from MeteoSchweiz for evaluating the visualisation process at the Open Research Data hackdays.
