{"version":"1.0","type":"rich","title":"Untitled","description":"This chart displays the population distribution across six U.S. states, broken down by seven age brackets. Each state’s data is shown as a group of colored bars, with a legend that allows users to click on age categories to filter which bars remain visible. The visualization uses D3 v5 with a band scale for grouping, a linear scale for the y-axis, and an ordinal scale for colors. It is rendered as an SVG, and clicking a legend item triggers a transition that updates the visible bars and rescales the axes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3c96fa64215342399f9dd870b0d0e336?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
