{"version":"1.0","type":"rich","title":"pie chart","description":"This pie chart visualizes country populations using D3.js v6, rendering each slice as an SVG path with a categorical color scale. The code loads CSV data from a GitHub gist, processes population values, and uses d3.pie() and d3.arc() to generate the chart geometry. Each slice is labeled with its country name positioned at the arc centroid, while a custom legend built from SVG rectangles and text elements displays the color assignments alongside the chart.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/515bf4fa216448e1b5f85ea7bd514050?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
