SoundCloud

SoundCloud is a simple data visualisation that shows the relationship between songs uploaded by the users/artist of Soundcloud (www.soundcloud.com). The application creates different ways of comparing songs by their meta-data. With smooth animations, the songs are arranged on the screen according to their duration, number of comments etc. This makes it easier for the user to find specific songs by their descriptive attributes instead of browsing through them one by one.

By selecting a parameter for the x and y-axis from the dropdown menu, users can see the relation between the number of times a song has been played and the number of comments it has received. By hovering the cursor over a song (represented by a square) lines are drawn to all the other songs by the same artist. In this way the user can compare relations between artist, songs and the meta-data of the songs. And it is of course also possible to listen to the songs.
