- A infographic showing my iTunes Library in which the songs are placed on the X and Y axis.
The position along the x-axis depends on the length of the song; short songs on the left, long songs on the right.
The vertical position is determined using the playcount of the song; the more I've listened to it, the higher it's placed.
Also, songs from the same album are connected using colored lines; one color for each album.

This way you get an image of your music-listening habbits; you can easily pick out the songs you really like and the songs you hardly ever listen to disapear in a big black stain.
