This example displays a horizontal bar chart of the ten most populous countries for 2020, using population values loaded from a remote CSV file. The chart is built with React and rendered as an SVG, leveraging D3 v7’s `scaleBand` and `scaleLinear` to position bars and axis ticks, and `csv` for data parsing. Gray gridlines mark each x-axis tick, while country labels appear along the vertical axis, with bar widths proportional to population.
