A horizontal bar chart maps country names to bar lengths, using the provided CSV data where each number is multiplied by 1000. Rects are appended to an SVG and positioned with `scaleBand` for the y-axis and `scaleLinear` for the x-axis, with bar widths proportional to the scaled values. The visualization uses d3.v5, specifically the `select`, `csv`, `scaleLinear`, `max`, and `scaleBand` APIs, rendering as static SVG output.
