Description
Depending on the number of categories and the amount of text in labels, the positioning of labels in pie-charts might be unsatisfying. The labels might overlap the title/subtitle. Here is an example image showing the problem:
This codepen contains relevant code for reproducing the issue.
There is also a related issue, which suggests adding an optional space between title and plot. But as this space would definitively depend on the actual data, I'd say plotly should handle this for the user automatically.

Research direction
Start with the linked CodePen reproduction and compare it with related issue #4932. Trace the pie-chart label layout behavior for varying category counts and label lengths, then verify that labels no longer overlap the title or subtitle while preserving readable positioning.
