This bar chart displays population sizes for ten countries, using horizontal bars whose lengths correspond to each nation’s population value. The visualization is rendered as SVG with D3 v5, employing `d3.scaleLinear` for the x-axis, `d3.scaleBand` for the y-axis categories, and `d3.axisLeft` and `d3.axisBottom` for the axes. Data is loaded from a CSV file and processed with `d3.csv`, with population values converted to numbers before rendering.
