Treemap is the densest/most accurate information source on a per px basis. Flamegraphs are pretty good but with a fixed Y and variable X your box area is inaccurate, and it wastes a fair amount of plot space with the non-flame area. The sunburst chart is really pretty but bad from an information communication perspective.
