{"version":"1.0","type":"rich","title":"Grouped Bar Chart","description":"This grouped bar chart displays state populations by age group, using color-coded bars for each age category across seven states. The visualization loads CSV data with d3.csv, encodes the x-position with d3.scaleBand and y-values with d3.scaleLinear, and assigns colors via d3.scaleOrdinal. It formats the y-axis tick labels with d3.format’s “s” SI prefix, computes domains with d3.max, and renders axes with d3.axisBottom and d3.axisLeft. A legend is appended manually, and the chart follows conventional margins with an SVG output.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-7c0ef2194253b52d5af88396d24c929b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
