{"version":"1.0","type":"rich","title":"Activity_7-Q1","description":"This example presents a D3.js pie chart visualizing categorical sales data loaded from a remote CSV file. The visualization uses `d3.csv` to fetch data, `d3.pie` to compute arc angles based on the Sales field, and `d3.arc` with an inner radius of zero to generate filled sectors. A `d3.scaleOrdinal` with `d3.schemeSet2` assigns colors to categories. The chart is rendered as SVG elements, with each path stroke outlined in white and semi-transparent opacity for visual distinction.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a3ed0cb72f274a1fa198dd84e3dab221?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
