{"version":"1.0","type":"rich","title":"Practice","description":"A donut chart of five colored arcs represents angular segments via D3's `arc` generator, with the final arc spanning a full circle from 3 radians to 2π. The SVG is centered using a group transform, and each path's `d` attribute is computed from hardcoded `startAngle`/`endAngle` data. The visualization uses `d3.select` and `d3.arc` with an inner radius of 60 and outer radius of 100, applying a small pad angle between segments. Colors come from a fixed palette, and the chart is rendered statically without interaction.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c87b5760d3be41e09abab429d8608a8b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
