How many curators are contributing playlists to the Free Music Archive?
The Free Music Archive (FMA) is project by the freeform radio station WFMU, which is based in Jersey City, New Jersey.
In line with WFMU's open access philosophy, the Free Music Archive provides a library of legal audio that anyone can download, and has a basic API that provides access to curator, album, artist and track data in JSON, JSONP and XML formats.
This visualisation calls in Free Music Archive curator data (specifically, the number of playlists each curator has contriubted to the FMA) via JSONP and displays the data as a scatterplot.
