This example shows a horizontal bar chart of population figures for the ten most populous countries, with each bar’s length proportional to its population value. The visualization loads data from a CSV file, converts the population strings to numbers, and renders the bars as SVG rectangles using D3 v5. It employs `d3.scaleLinear` for the x-axis, `d3.scaleBand` for the categorical y-axis, and `d3.axisLeft` and `d3.axisBottom` to generate the axes.
