This bar chart displays population figures for five countries using steelblue circles positioned by a linear x-axis and point-scale y-axis. The React-based visualization loads data from a CSV file and renders as SVG using D3’s `scaleLinear`, `scalePoint`, `axisBottom`, and `axisLeft` APIs. Grid lines extend across the plot area, and x-axis tick labels abbreviate large numbers using `format('.2s')`.
