{"version":"1.0","type":"rich","title":"Pie chart RDW","description":"This example displays a pie chart of yearly values using D3.js, rendering four labeled slices with a categorical color scheme. The visualization is built with the `d3.pie` layout function and `d3.arc` for paths and labels, rendered as SVG. It uses `d3.scaleOrdinal` for colors and `d3.schemeCategory10` for the palette, with data hardcoded in the script. The chart is centered using an SVG group transform, and each slice’s year is placed via the label centroid.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c9680de45ab9484e8362a2f30048b659?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
