{"version":"1.0","type":"rich","title":"Activity_7","description":"This example visualizes market share by category as a pie chart with a sorted legend showing each category’s percentage. It loads CSV data from a remote GitHub source, computes arc positions with `d3.pie` and renders slices via `d3.arc` into an SVG. A `d3.scaleOrdinal` with `d3.schemeCategory10` assigns colors, while the legend displays sorted percentages beside the chart. The code demonstrates D3 v6 loading via UNPKG and local ES6 module imports.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/373ae25db4924efe9aff31b82d61947f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
