There might be a chance to use it for something like that. It really has
nice interactive charts.

But still I think some work would have to be done to get the 'hamster'
data model to fit that from arbtt.
Arbtt has not such a concept of having _one_ activity name for every
sample it takes. So it is kind of hard to come up with a specific name.
True, you can use their tags.
I tried this the other day. You can have a look [1] :)

Even if we get the 'hamster' to cooperate with us I think there is a
performance issue, since arbtt is collecting a lot of data and the
charts are not even really responsive on my machine with the little data
I've collected so far.
And it kind of feels strange to call a python program to do the drawing.

Do you have an idea which chart drawing library we could use? I know
there is Chart on hackage but it pulls gtk2hs in. Not sure if it's a bit
of an overkill.
