This scatter plot visualizes the top 10 most populous countries using a CSV data source. The code uses d3.scaleLinear for the x-axis (population) and d3.scalePoint for the y-axis (country names), with circles rendered as SVG elements. D3's axisLeft and axisBottom generators, along with custom tick formatting via d3.format, display the axes. The chart includes gridlines, labeled axes, and a title, all styled through external CSS.
