I am a user of last.fm since 2005 and I’ve always tried to scrobble as much music as possible (34.711 songs scrobbled at present). Last.fm let’s you have an historical archive of your music listening habits, which is cool but I always missed to have an overview from the point of view of the artist. Is a musician being listened more than last year? Is an artist more listened after an album release? What happens when they are on tour? Could we visualize a change on a listener’s behavior due to specific events?

One effect I wanted to visualize is a likely increase of the artist’s playcounts after he dies. One can assume that the number of playcounts increase, but how long does this effect? Which artists get the greatest increase on their playcounts? So I built a data visualization in order to get some insight about the effects of an artist’s death:

Recently I was asked to develop an online interactive piece for the University of La Rioja (UNIR) that allowed readers to explore the crimes in Spain on a number of different metrics.

This piece provides an interactive map, allowing the user to display the crime distribution in Spain based on different criteria such as crime type and subtype, crime status and year.

It was a funny assignment as it covered all the process: starting with preparing all the data and ending with providing visualization and interactivity of the piece.
