{"version":"1.0","type":"rich","title":"Stacked Radial Bar Chart example.","description":"This stacked radial bar chart displays the population distribution across seven age groups for each U.S. state, using concentric rings to encode values. The chart is rendered as SVG with D3 v7, using `d3.scaleBand` for angular positioning, `d3.scaleRadial` for radial distances, and `d3.stack` to create the layered segments. Color is assigned via `d3.scaleOrdinal`, with helpers for axis labels and a legend. Data comes from a CSV file with state-level census figures.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b1c94ccabc7c4ff394bf15378561a025?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
