This bar chart displays population figures for ten countries, with each bar’s width proportional to its population using a `d3.scaleLinear` for the x-axis and a `d3.scaleBand` for the y-axis to position countries. Data is loaded from a CSV via `d3.csv`, with population values converted from strings to numbers. The chart renders as SVG rectangles inside a fixed 960×500 viewport, using D3 v5’s data join to append elements. The code omits vertical bar positioning, leaving the default y-coordinate, while the x-scale domain spans from zero to the maximum population.
