It would be nice if we would have some kind of interactive UI where we could visualize how the ownership changes over time.
E.g. we could use a slider for the different check-ins and a tree map that visualizes the information for the specific check-in. So when moving the slider then the treemap would immediately update and reflect the new state.
The idea is to see whether ownership, bugs, etc. stays the same over time or follows some kind of pattern (e.g. bugs are following new code that is at most 2 weeks old / is developed by specific teams). So it would be possible to identify some lacks of knowledge etc.
