This example displays a bar chart of the top ten countries by 2020 population, using a horizontal layout where each bar’s length is proportional to the population value. The visualization is built with React, using D3 utilities for data loading and scaling: `d3.csv` fetches the UN Population dataset, while `d3.scaleBand` and `d3.scaleLinear` map countries and populations to SVG rectangles. The SVG output is rendered inside a React component, with margins applied via a translation transform.
