This bar chart visualizes the populations of ten countries, with horizontal bars representing each nation's population in thousands. The chart uses a linear scale for population values and a band scale for country names, with axis labels and steel-blue colored bars. Built with D3 v5, the visualization reads data from a CSV file and renders as an SVG, using D3's scaleLinear, scaleBand, axisLeft, and axisBottom functions to construct the chart.
