{"version":"1.0","type":"rich","title":"[TEST] Pie Chart","description":"This test pie chart demonstrates the proportional breakdown of credit rating categories, with \"AAA Local\" dominating the visualization. The chart renders as a standard donut without labels on the slices themselves, instead using a legend on the right to identify each category and its corresponding percentage. Built with D3 v5, the code uses `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` to transform the JSON data into SVG path segments, while `d3.format` handles the numeric tick formatting for the legend values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/22a0cc7854424e32bc3b9bcde8ca6ebd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
