{"version":"1.0","type":"rich","title":"Untitled","description":"A radial stacked bar chart displays the population distribution of U.S. states across seven age groups, using a circular layout with state labels around the perimeter and a legend on the left. The visualization is rendered as SVG with D3 v4, employing `d3.scaleBand` for angular positioning, a custom `d3-scale-radial.js` for radial distances, `d3.stack` for segmenting data, and `d3.arc` to draw the bars. Data comes from a CSV file with state-level age bracketed counts.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c75cc66fcfb445cf9be3ce0e829e970e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
