A horizontal bar chart displays population figures for the ten most populous countries, with bars labeled by country name along the y-axis and a linear population scale on the x-axis. The visualization uses D3 v5 APIs including `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to construct the chart. Data is loaded from a CSV file using `d3.csv`, with population values multiplied by 1000 for display. The SVG output renders steelblue rectangles with a font size of 1.5em for text labels.
