Feature suggestion - venn diagrams

I would like to suggest a feature that I think could be useful.
I saw that you already support scatter plot - which scales by the size of the circle and I think it's halfway to support venn diagrams.
I think that the diagram should be hoverable - so if you hover on a specific intersection you could see some details about it like the size of it or the elements in it.
The same goes for a click listener - so you can execute some functions based on a click on a specific intersection.

I specifically have been searching a flutter package that supports this feature for a long time and didn't find any, and I believe that supporting a unique feature that others don't, may also increase the numbers of users using the package.

Let me know if you are considering this feature.

Start by reviewing the existing scatter-chart support in the Flutter package and how chart interactions are handled. Define the Venn diagram data model and rendering scope before implementation; done should include hover details and click callbacks for specific intersections, with tests covering those interactions.
