{"version":"1.0","type":"rich","title":"Fork of ice-7 q2","description":"This example shows the distribution of air quality categories—such as Good, Moderate, Unhealthy, and Unhealthy for Sensitive Groups—as a pie chart with an interactive legend and tooltip. Using d3.rollup to aggregate counts from a hardcoded dataset, the SVG chart assigns each category a color-coded slice and displays its proportion. The code relies on D3 v7’s pie and arc generators, plus d3.select for DOM manipulation, with a tooltip that appears on hover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8ed369aa09094f7cbc678feb532600ed?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
