This example shows a bar chart of global video game sales by genre, with bars rendered as SVG rectangles whose heights are scaled by sales figures. The code loads CSV data using `d3.csv` and manages state with React hooks (`useState`, `useEffect`), while `d3.scaleBand` and `d3.scaleLinear` map genres and sales values to pixel positions. The chart is drawn entirely through React components that return SVG elements, demonstrating a hybrid approach where D3 handles data processing and scales, while React handles the DOM rendering.
