{"version":"1.0","type":"rich","title":"Fork of Hello VizHub","description":"This example presents a pie chart of engine efficiency across various vehicle types. The D3.js code builds the visualization using the `pie` and `arc` generators, rendering SVG paths for each slice and a legend with colored boxes and formatted text labels. The chart's data is hardcoded within the script, and colors are assigned via `scaleOrdinal` with the `schemeCategory10` palette. The final visualization includes a title and a legend positioned to the right of the pie.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4b011c03514545c9985bb6359ce4cb64?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
