{"version":"1.0","type":"rich","title":"Assignment 2 - Pie Chart","description":"This pie chart visualizes vehicle registration counts by type, with each slice labeled with its value in thousands and accompanied by a color-coded legend. The visualization uses D3 v5’s `d3.pie` and `d3.arc` to generate the chart, `d3.scaleOrdinal` for slice colors, and `d3.format` for tick labels. Data is loaded asynchronously from a CSV file via `d3.csv`, and the chart is rendered as SVG with custom styling for text and legends.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8c64fb3d44d749ad83d509fd70fdf5f2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
