{"version":"1.0","type":"rich","title":"pie chart ice 7","description":"This pie chart visualizes website traffic source distribution using a React component with D3.js v5. It loads CSV data from a GitHub gist and renders slices with `d3.pie` and `d3.arc`, colored by `d3.scaleOrdinal` with `schemeCategory10`. Hovering a slice displays a tooltip via D3 selection showing the source, visitor count, and percentage. Labels are positioned using arc centroids, with a legend omitted. The chart updates reactively through React’s `useState` and `useEffect` hooks after asynchronous data loading.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/95a61900b726430dbdcdae4d22c176f3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
