The bars are rendered as SVG rectangles using React components, with scales created via `d3.scaleBand` and `d3.scaleLinear`. Axis ticks are formatted using `d3.format` to convert values to billions. The data is loaded from a CSV file using `d3.csv`, and the chart includes tooltips via SVG `<title>` elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3a7a7ec4a5e2449eb1ef6b521d88792e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
