This example shows a horizontal bar chart of national populations, using the ten most populous countries from a CSV file. The chart renders as an SVG and uses D3 v6 scales (`scaleLinear` for bar lengths and `scaleBand` for categorical y-axis placement), with `d3.axisLeft` and `d3.axisBottom` providing labeled axes. Population values from the data are multiplied by 1,000 before plotting, and bars are colored via a CSS rule targeting `rect` elements. The React framework is present in the starter code but does not drive this visualization directly.
