This bar chart displays the populations of the ten most populous countries, with horizontal bars ordered by country name. The visualization reads population data from a CSV file and renders it as SVG using React and D3 v5. The code leverages D3’s `csv` loader, `scaleLinear` for the x-axis, `scaleBand` for the y-axis, and `axisLeft`/`axisBottom` to generate the chart’s axes.
