The visualization uses React with D3's `scaleBand` and `scaleLinear` to position bars and axes, rendering to SVG.

Data is loaded asynchronously from a CSV file via `d3.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/15487948902e41f19470346ce74d129d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
