A horizontal bar chart displays population estimates for ten countries, sourced from a CSV file. The chart encodes population values as bar lengths using a linear scale, while country names are positioned along a band scale. Built with React and D3 v5, the visualization renders as SVG and uses `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to construct the axes and bars. Data loading and parsing are handled by D3’s `csv` function.
