What it actually does
A two-ring radial hierarchy chart — the inner ring shows main segments and the outer ring shows their sub-categories.

Behavior controls: “Label Font Weight” options: 400 Regular, 500 Medium, 600 Semi-bold, 700 Bold.
Sunburst Chart has no render.php and no frontend.js. The saved Gutenberg HTML is what visitors see, plus Blockenberg layout/typography CSS.
