{"version":"1.0","type":"rich","title":"fresh block","description":"A pie chart displays the percentage distribution of values from a CSV file, with each slice labeled by its share of the total. The visualization uses D3 v4’s `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` to compute angles, draw SVG paths, and assign a categorical color palette. Labels are positioned via `labelArc.centroid` and formatted with `d3.format`. Data is loaded asynchronously with `d3.csv`, and the chart is rendered as SVG centered on a 960×500 canvas.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-fe387d2be823742488911f28875f2df3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
