The chart is rendered in SVG via D3.js v7, using `d3.csv` for data loading, `d3.rollup` for aggregation, and `d3.scaleBand` and `d3.scaleLinear` for positioning. CSS hover effects change bars from steelblue to orange, while axis labels are added via `d3.axisBottom` and `d3.axisLeft`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d5dfe9059851436bbbc56f26ce300608?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
