{"version":"1.0","type":"rich","title":"Pie chart Test","description":"This example shows a simple pie chart of browser usage, displaying four labeled slices with a legend-like color scale. The visualization is rendered as an SVG element using D3 v6, with data hardcoded in the script rather than loaded from the CSV file. The code uses `d3.pie()` to compute arc angles, `d3.arc()` to generate path data, and `d3.scaleOrdinal` for color mapping. Each slice includes a text label positioned via `label.centroid()`. The chart is centered on the page using CSS transforms.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5238b19a282c488d9baf258b2a9c7deb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
