This example displays a horizontal bar chart ranking the populations of ten countries using data from a UN Population CSV file. React hooks manage the data-fetching state, while D3’s `scaleBand` and `scaleLinear` map country names and population values to SVG rectangles rendered inside a React component. The visualization includes styled axes with formatted tick labels (using D3’s `format`), a labeled x-axis, and a tooltip on each bar via the SVG `<title>` element, all styled with the Poppins font.
