A donut chart is a circular data visualization that encodes part-to-whole proportions as angular segments of an annular ring, with a hollow center that can display a summary value or label. The parameter is the number of categories (minimum two), each mapped to an angle proportional to its share of the total. It persists as a static or interactive graphic rendered on a display medium, optimized for comparing relative magnitudes of a small set of categories where the viewer already knows the whole. [formal: annulus | substrate: mind | horizon: a moment | explicit: yes | epoch: 1.01]
