The bars are colored a light green, with blue axis ticks and a labeled x-axis in billions. The code uses React hooks—`useState`, `useCallback` and `useEffect`—to load CSV data via `d3.csv` from a GitHub repository, then renders the chart with `d3.scaleBand` and `d3.scaleLinear` as SVG elements, formatting tick labels using `d3.format`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1dda8076b16e40049f7cb3ecb5adc4b7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
