{"version":"1.0","type":"rich","title":"UPW Pie Chart","description":"This pie chart displays the distribution of United Packing City visits in 1958 by brand, showing each brand’s percentage and total value in thousands. The visualization loads CSV data from a GitHub gist via `d3.csv`. Using `d3.pie` and `d3.arc`, it generates SVG paths with `d3.scaleOrdinal` for color coding. Legends are appended manually, with values formatted using `d3.format`. The chart is rendered entirely with SVG and styled through external CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/952c37af688846bcafedbb32ed563dea?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
