{"version":"1.0","type":"rich","title":"Untitled","description":"This stacked bar chart displays the total population for each state across selected years, with bars segmented by three categories. A dropdown menu lets viewers switch between years, triggering a smooth transition that updates bar heights and the y-axis scale. The visualization is built with D3.js v5, using d3.stack for data aggregation, d3.scaleBand and d3.scaleLinear for positioning, and SVG transitions to animate changes. Data comes from a local CSV file, with each bar labeled with its total value.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/12e242c71efa45318ae8b1c389c9f255?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
