{"version":"1.0","type":"rich","title":"Untitled","description":"This interactive stacked bar chart displays state-level data across two years. A dropdown menu selects the year, and the visualization animates the transition between the 2017 and 2018 views. The chart uses a categorical color scale to distinguish three data ranges. The code leverages D3 v5 APIs including `d3.csv`, `d3.scaleBand`, `d3.scaleLinear`, and `d3.stack`. Built with SVG elements, the bars and their total value labels are rendered directly, with a 750ms transition on year change.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/47caa4f1d0d340f686051b15b9e27c7c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
