Implementation

modelTunes is realized by processing. The visualized data is provided in XML format at Audioscrobbler web page. The specific data used in this visualization are weekly artist lists for a specified user and artist similarities.

After the data is captured, a simple Self Organizing Map (SOM) algorithm arranges artists for every week according to their similarities. Original two dimensional SOM algorithm is reduced to one dimension. After each week is arranged independantly, they are slided on horizantal axis so that most frequently played artists are aligned on vertical axis. After placements are done, each artist is connected to its first reapparance with a bezier line. If there is no reappearance then square corresponding for that artist is dehighlighted with a dim red color.
