{"version":"1.0","type":"rich","title":"pie chart","description":"This pie chart displays the proportional sales distribution across countries for the year 2020, using a dataset of students loaded via `d3.csv`. The visualization renders each country as a colored slice with labels positioned at the centroid of each arc. It uses D3 v7’s `d3.pie()` and `d3.arc()` generators to compute and draw the arcs, with `d3.scaleOrdinal` and `d3.schemeCategory10` providing categorical colors. A legend on the right maps colors to country names, and the SVG output is created within a fixed 600×400 pixel canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/637cf25719dd4014a08a09d8f4940737?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
