Improve donut plot

[fdebrain]

Is your feature request related to a problem? Please describe. Make the donut plot more useful, appealing and customizable.

Describe the solution you'd like Here are a few improvement ideas:

• Adding count/percentage text labels on top of the donut plot (but hide if small segment)
• Adding the option to subsegment with another categorical feature (see additional context)
• Improve interactivity (hover tooltip, legend, etc...)
• Customization (inner/outer radius, colors, text size)

Describe alternatives you've considered You will probably need to get familiar with Vega-Lite

Additional context This is currently how it looks in the app:

Hi @fdebrain, I did a PR adding a new tab to create a complex donut chart, this wasn't easy for me but it's an initial improvement. I will wait for your comments.
