{"version":"1.0","type":"rich","title":"Fork of Hello VizHub","description":"This example displays a D3.js pie chart that visualizes the distribution of insurance records by region, rendered as SVG with an accompanying legend and interactive tooltips. The code loads CSV data from a GitHub-hosted dataset using `d3.csv`, aggregates region counts with `d3.rollup`, and constructs the pie with `d3.pie` and `d3.arc`. Hovering over a slice highlights it, triggers a tooltip showing the category and value, and applies categorical colors from `d3.scaleOrdinal` and `d3.schemeCategory10`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/65a92033b1db417eb14f55c5e34e6f12?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
