{"version":"1.0","type":"rich","title":"Fork of Pie Chart","description":"This fork of Observable’s pie chart example embeds an interactive D3.js (v5) visualization via an iframe into a minimal HTML page. The chart renders the U.S. population by age group, using `d3.pie()` and `d3.arc()` to draw wedges, with a spectral color scale and labels positioned by `d3.arc().centroid`. Data comes from a local CSV file. The styling is handled with CSS, and the code leverages Observable’s `PieChart` function.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b6bf8f84540047719967e0f2a8862bc3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
