{"version":"1.0","type":"rich","title":"1","description":"This example shows a pie chart of country populations, with each slice labeled by country name and a legend mapping colors to countries. Hovering over a slice’s label displays a tooltip with the population (formatted with commas) and literacy rate. Built with D3 v7, the visualization uses `d3.pie()` and `d3.arc()` to generate SVG paths, while data is loaded via `d3.csv()` from a GitHub gist. The tooltip is manually shown and hidden through D3 selection and style updates, and colors come from `d3.schemeSet3`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/28dddf845b0d476f8de1d8c9bc5898c5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
