This visualization displays the top five countries by population using a horizontal bar chart. The bars are rendered as red SVG rectangles within a React application, with blue grid lines and axis labels. The code employs D3.js modules including `csv`, `scaleBand`, `scaleLinear`, and `max` to load and scale the data. The chart is built with React's `useState` and `useEffect` hooks, while ReactDOM renders the final SVG output. Data is fetched from a CSV hosted on GitHub gists.
