{"version":"1.0","type":"rich","title":"piechart question1LB","description":"This pie chart visualizes vehicle registration counts by type, with each slice labeled with its abbreviated value (e.g., \"15K) and accompanied by a color-coded legend showing both the category name and exact count. The chart loads CSV data from a GitHub gist using `d3.csv`, then constructs the pie with `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` for color mapping, while text labels are positioned via `arc.centroid`. Rendered as SVG, the visualization uses D3 v5 selection methods to append paths and legend elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b20ad18aa3e347ff83b3ee082213e20f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
