{"version":"1.0","type":"rich","title":"Pie Chart","description":"A pie chart displays GDP per capita for ten countries from a CSV file, with color-coded slices and a legend showing country names and GDP values in billions. Built with D3 v5, the visualization uses `d3.pie()` and `d3.arc()` to generate SVG paths, `d3.scaleOrdinal` for color mapping, and `d3.format` for numeric labels. The data is loaded asynchronously via `d3.csv` from a gist URL, and the legend is manually positioned with rect and text elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f13382efda754054bc5d5e8246bbd0c7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
