This example displays a horizontal bar chart of the five most populous countries, using data from a CSV file that is loaded via D3’s `csv` utility. React’s `useState` and `useEffect` hooks manage the asynchronous data loading, while the chart itself is rendered as SVG rectangles. The scales are created with `d3.scaleBand` and `d3.scaleLinear`, and the bar widths are proportional to the population values. The visualization is built with React and D3 v7, with the graphic element rotated by a degree value, though the rotation animation is commented out.
