Sunburst with evolution per month
MargNIOP, let me know if this will work. I did my best to try and make sure that the capability labels do not overlap. The tooltip only shows if there has been a change from one month to the next. I didn't do anything with the stacked bar chart, but the stacked bar chart that comes with Power BI should be able to fulfill your needs.
If this is enough to get you going please consider liking this reply and choosing it as the solution. Otherwise, I'm happy to help further.
Hi MargNIOP I was having some trouble getting it to look how you described. The sunburst is a hierarchical chart where the items higher up in the hierarchy are closer to the center. Since you wanted a rolling sum, it actually makes sense to have the months to be in the order starting from outside to inside. This will show that cumulation that you were describing (note how the arc angles for each category get larger the closer you get to the center). Additionally, instead of using color for the months, I found that it made sense to use color for the categories, and then use labels to show which "rings" represent which months. I also included labels for each category.
I know that these are pretty significant deviations from which you first proposed. Let me know your thoughts and suggestions. I want to get the design right before getting it into Deneb and Power BI.
Here is a gist that allows for tooltip interactivity and shows how it was implented in Vega.
