{"version":"1.0","type":"rich","title":" 2.1.1","description":"This pie chart visualization displays the Air Quality Index (AQI) by country, with each slice sized proportionally to the index value. The data loads from a CSV file, with the index parsed as a numeric value and countries sorted in descending order. Using d3.pie and d3.arc, the SVG renders colored slices, a legend with country names and formatted index values, and a title. A d3.scaleOrdinal with schemeCategory10 assigns colors, while the chart groups transform to center the pie.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2664f220d64d47a398eabab1816a061f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
