This chart displays the populations of seven countries as horizontal bars, with bar length proportional to population and each country labeled on the y-axis. Built with React and D3, it loads data from a CSV file, scales the population values by a thousand, and uses `d3.scaleLinear` for the x-axis and `d3.scaleBand` for the y-axis. The visualization is rendered as SVG elements within a 960-by-500 canvas.
