So, I've implemented a first draft of this. But now I've got a little
problem:
if each url get's its own column in the graph, it will look *really*
awful for e.g. the /tags/ folder. Think about it: each tag will get its
own column.

Do you have a suggestion on how to prevent this or make the graph look
nicer?
