This horizontal bar chart displays the 15 largest countries by area, using D3.js v5 to map country names to a band scale on the y-axis and area in square miles to a linear scale on the x-axis. The SVG rendering includes axis labels, a title, and gridlines, with data loaded from a CSV file via `d3.csv`. The code applies a custom tick formatter to abbreviate large numbers, and bars are styled with CSS.
