Texts and nodes are far too small in the heatmap export

[tommv]

The heatmap export is really really cool.
The texts and nodes that it contains however are really really small and actually almost invisible (see the attached example).
Is it OK is the smallest texts and nodes are tiny, but the biggest (= occurring in many records) should be much bigger.

NB. I am fully aware that this means that in some cases there will be overlaps, but that's fine. Overlaps are easy to manually correct in a design software, while the current problem is impossible to fix manually.
