What does this treemap show?
It shows project structure with folders sized by
amount of file changes or amount of unique committers.
Amount of file changes can be useful to see the most actively changed parts of project (note that amount of file changes is not the same as amount of commits in folder).
Amount of unique committers can show parts of project with highest/lowest amount of collaboration (note that amount of unique committers in parent folder is not the sum of its children's amount because of overlap between sets of committers).
Folders/files which are too small to be displayed are merged into '[...]' tile under their parent.The size of tiles in treemap is only proportional within parent tile.
