[feature request] Per-category pie chart

[yantar92]

It would be handy to summarise the clock data in pie chart, grouping the clocked data by category. Something similar to what Sasha Chua does in her weekly review [1]

Will look into that.

Firstly, thanks for this great visualization tool! This would be very useful, either by category or by tag. Not necessarily as a pie chart (in my case), but as a table with a total time spent per category/tag and a percentage of the total. This would be useful to see what percentage of time goes into what kinds of activities (e.g. professional, family, social, etc.).
