This example shows a horizontal bar chart of population by country, using a CSV dataset for 10 nations. It builds an SVG chart with D3 v7, mapping population to bar width via `scaleLinear` and country names to vertical bands with `scaleBand`. The code uses `axisLeft` and `axisBottom` for labeled axes, and appends `rect` elements for each row. Styling applies a steelblue fill to the bars.
