{"version":"1.0","type":"rich","title":"Pie chart","description":"This example shows a donut-style pie chart that animates between two datasets after a three-second delay. The initial render displays four categorical slices sized 100,000, then re-renders with five new proportions representing a different dataset. The chart uses d3.pie to compute arc angles and d3.arc with an inner radius to create the donut shape, while a d3.scaleOrdinal assigns categorical colors. The visualization is drawn as SVG elements, and both datasets are hardcoded in JavaScript.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1170a1c3e13948cca7efb79d8362cafb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
