{"version":"1.0","type":"rich","title":"Pie Chart","description":"This pie chart displays categorical data loaded from a CSV file, with slices colored by category and labeled directly on the chart. It uses D3.js APIs such as `d3.pie()`, `d3.arc()`, and `d3.scaleOrdinal` with `d3.schemeCategory10` to generate and color the SVG paths. Text labels are positioned using `arc.centroid`, and a legend is built with appended rectangles and text elements. The SVG is centered via a transform, and the chart dimensions are fixed at 500 by 500 pixels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/603a7f4d75db4dc5af7faabb683c3d3b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
