This example displays a horizontal bar chart of the top 10 countries by population, using D3 v7 to render SVG rectangles. The chart uses a linear scale for the population axis and a band scale for country names, with axis labels generated via `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom`. Data is loaded from a CSV file and processed by multiplying population values by 1000 before rendering, with the bar color set to steelblue via CSS.
