CwDonutChart renders proportional segment totals with hover feedback. Build the `segments` array first, then adjust chart size and thickness to fit the layout.

How to think about it

  1. Model your data as labeled totals Each segment needs a `label` and `value`, with optional `color` when the defaults are not enough.
  2. Tune size for the container Use `size` to fit the available space and `thickness` to control how heavy or airy the ring looks.
  3. Hide the legend only in cramped layouts The legend improves readability, so turn it off only when the surrounding UI already labels the segments.
