Help! How do I use this?

This web application uses a last.fm user's listening history to generate a streamgraph of his listening activity.

Enter a last.fm username into the "Username" field, and set the date range you want to observe with the "From" and "To" options. Use the "Minimum plays" field to fine-tune the resulting graph by only showing those artists above the provided minimum plays value.

The slider at the bottom of the generated streamgraph can be used to zoom into and pan across the graph.
