Today I was searching for a website with information about the iTunes Top100 by genre. I could have just opened up iTunes to see this, but I was looking for something more. What I found was a Treemap that tracks the iTunes Top 100 songs as they move up and down the charts - updated daily.
On the treemap, each square represents a song. You can view song details by moving your mouse over each square on the map. Clicking on a song allows you listen to the track, purchase the track or view other information in iTunes.
The map default setting organizes by Genre, but you can switch it to organize by chart position as well. The size of each song's square represents either the songs chart position or the # of days in the top 100. The color of the song's square represents the 24 Hr Change in Chart Position. Songs moving up the charts appear Dark Orange and songs moving down the charts appear Dark Blue. There are further customizations you can make such as focusing on songs moving up (or down) in the charts, but I think you get the general idea of this tool. Its a pretty cool way of checking out the top 100 iTunes music.
This Treemap was built by the Hive Group as a demo of their companies mapping information capabilities. Check out the iTunes TreeMap at the Hive Group.
