Last week I covered a variety of Last.fm visualizations. One of the most promising of the bunch is an online utility called LastGraph. When I first tried to use the service it was offline. Now its back up, working great and sporting some cool new features. Basically, LastGraph takes your Last.fm listening behavior within a certain date range and creates a really beautiful wave graph of it. The updated version now lets you select from a variety of color schemes in addition to the classic Ocean theme. I did have problems opening the generated PDFs in Preview but when i rasterized them via Photoshop, they showed up no problem. There is also a Flickr group to upload your own graphs. Have a friend on Last.fm? For their next birthday, use this tool to generate a giant poster of their listening behavior.
