{"version":"1.0","type":"rich","title":"Ozone AQI Count by Days","description":"This example shows the number of days each ozone AQI category occurred, displayed as a pie chart with a legend listing each category and its day count. The data is loaded from a CSV file via `d3.csv`, then processed into a form suitable for `d3.pie` and rendered as SVG paths using `d3.arc`. The chart uses `d3.scaleOrdinal` with `schemeCategory10` for coloring, and a custom legend built with SVG rectangles and text. The visualization is implemented in React with D3 v5, and the SVG is updated on mouseover to log category counts.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7a248d6d458e4c96a59259047a14d4fd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
