{"version":"1.0","type":"rich","title":"Question1","description":"A pie chart visualizes population distribution across Indian states, with each slice labeled by state name and percentage of the total population. The chart uses D3 v7's `pie` and `arc` generators to compute slice geometry, `scaleOrdinal` with `schemeCategory10` for colors, and SVG `path` elements for rendering. A custom legend displays each state's name, population in millions, and percentage, while labels positioned via `arc.centroid` show percentages directly on slices. Data comes from a CSV file loaded with `d3.csv`, formatted with custom number and percentage helpers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/efa1a58de23a4941a5c5f27a1e3d0367?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
