A horizontal barchart displays population counts for ten countries, with bars sorted from largest to smallest and value labels placed along the top axis. The visualization uses React with D3 v5, loading data from a CSV file and rendering as SVG. It employs `d3.csv`, `scaleLinear`, `scaleBand`, and axis generators (`axisLeft`, `axisBottom`, `axisRight`) to position bars and ticks. The code explicitly multiplies population values by 1000, and styling uses a steelblue fill for rectangles.
