Donut (doughnut) charts display part-to-whole proportions as a ring of slices with a hollow center. That center area is perfect for embedding descriptive text, making the chart self-explanatory without an external title or legend.
This sample visualizes console operating system market share for Android, PlayStation, Wii, and Xbox. A standalone label placed in the 60% inner radius displays the chart title text. Each slice is styled with a custom distinct palette and a darkened outline derived from its fill color, while the tooltip shows formatted percent values for quick comparison on hover.
