{"version":"1.0","type":"rich","title":"Making an Interactive Pie Chart","description":"This interactive pie chart visualizes university funding amounts, with each slice labeled and color-coded by institution. Built with D3.js v5, the chart uses `d3.pie` and `d3.arc` to generate the donut geometry and `d3.scaleOrdinal` with `d3-scale-chromatic` for slice colors. Hovering over a slice triggers a tooltip showing the percentage of total funding, calculated via `d3.sum` and `d3.event`. The data comes from a CSV file loaded asynchronously, and the visualization renders as SVG with hover opacity effects and rounded slice corners.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1b777e153e9c48c8a1675aa7011b5892?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
