Erroneous legends in the categorization bar chart
Somehow the legends in the categorization bar chart do not match the bar sizes. The script seems to always the stack the bars in the same order which does not match the label order (which is the order in which the data is provided). In commit 97aa2550 this is fixed by ordering the data by hand in categorization.csv. However, if this file is re-generated the ordering will be wrong again.
