This bar chart visualizes the population of the ten most populous countries, using horizontal bars to compare values. The chart is rendered as an SVG using D3 v5, with a linear scale for population values and a band scale for country names. The data is loaded from a CSV file and multiplied by 1,000 to display the actual population numbers. The chart uses `d3.scaleLinear`, `d3.scaleBand`, `d3.axisLeft`, and `d3.axisBottom` to construct the axes and bars.
