{"version":"1.0","type":"rich","title":"activity 7.1","description":"A D3.js pie chart displays the proportional values of twenty product categories, with each slice labeled directly on the chart. A legend on the right side maps category names to their corresponding colors. The visualization uses `d3.pie()` to compute arc data, `d3.arc()` to generate path and label geometry, and `d3.scaleOrdinal(d3.schemeCategory10)` for categorical coloring. The SVG is rendered at 800x600 pixels, with the pie centered on the left half of the canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4956c128c2ac43dfa5e0e5fcb9c63100?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
