{"version":"1.0","type":"rich","title":" Pie Chart","description":"This pie chart visualizes monthly expense categories from a CSV file, displaying each category's proportion with a colored slice and an outer label. Each slice is rendered with the `d3.arc` path generator, while labels are placed using `d3.arc` centroid calculations. A legend lists categories and values, using `d3.scaleOrdinal` with `d3.schemeCategory10` for colors. The chart is built with D3 v7, rendering to SVG, with the `d3.pie` layout function computing slice angles from the data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ea4871e5c5c7498a9225d8cbf0252315?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
