This bar chart displays the 2022 population of three countries using horizontal bars, with country names on the y-axis and population values on the x-axis. It uses React with a D3.js v5 backend, employing `scaleBand` for the categorical y-axis, `scaleLinear` for the numeric x-axis, and `csv` to load data from a remote GitHub gist. The chart renders as an SVG, drawing grid lines, axis labels, and rectangles for each bar.
