This horizontal bar chart displays the population of various countries. The visualization uses a linear scale for the population values on the x-axis and a band scale for the countries on the y-axis. The chart is rendered as an SVG using d3.scaleLinear, d3.scaleBand, d3.axisLeft, and d3.axisBottom. Data is loaded from a CSV file, with the population values multiplied by 1000 upon parsing.
