{"version":"1.0","type":"rich","title":"tutorial","description":"This example shows the distribution of highway fuel efficiency across car brands as a pie chart. Each slice is labeled with the brand name and its corresponding percentage of highway MPG. The visualization loads CSV data from a GitHub repository and uses D3’s `pie` and `arc` generators to create the slices, with `scaleOrdinal` assigning colors per brand. Labels are positioned using `arcGenerator.centroid`, and the SVG is centered within the viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d492c59ec1d749fdaf95fcddf8ea74e3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
