{"version":"1.0","type":"rich","title":"circles on circle pie","description":"A radial pie chart displays demographic proportions of men and women in Russia, using 100 small circles arranged around a larger circle. Each dot’s color corresponds to one of two categories, with the boundary between colors determined by a threshold scale. The chart uses d3.v4 with SVG, computing angles in radians and positioning dots via trigonometric functions. A legend shows percentages and category names, while an inner grey circle outlines the main structure. Data is hardcoded as an array of population counts.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-b3f051efd3c577fe73749e809a77b766?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
