Donut (doughnut) charts display part-to-whole proportions as a ring of slices, with a hollow center that distinguishes them from standard pie charts. Adding 3D mode gives the ring a three-dimensional perspective for a more visually striking presentation.
This sample renders a 3D donut chart showing the world’s main sources of energy measured in ZJ (zettajoules). Six categories — from oil shales and heavy oil to proven reserves and unrecoverable resources — are displayed with an inner radius that creates the donut hole and a compact 43% outer radius. The interactive legend allows clicking slices to explode them and hovering to highlight.
Follow the step-by-step Donut Chart Tutorial to learn how such charts are built. See the Donut Chart documentation for all configuration options.
