Known issues & how to tackle them

Treemap nodes sometimes switch position

That happens because sticky is set to false, but we need sticky false because the number of elements in the dataset is not constant. sticky false results in recalculations of the treemap layout everytime the data has changed.

How to fix: Keep the data nodes count constant and set nodes that don't exist to weight = 0 => we can use sticky true => no jumping treemap nodes & better layout caching :-)
