This horizontal bar chart displays the top 10 most populous countries in the year 2000. The visualization uses D3 v7 to load CSV data from a remote GitHub repository and render light green SVG rectangles, whose widths correspond to population values sorted in descending order. The chart employs linear and band scales for positioning, with formatted tick labels converting large numbers to abbreviated units. Axis components and marks are modularized into separate files, and margins define the plotting area within an 800×500 SVG canvas.
