This bar chart displays the population of ten countries from a United Nations 2019 dataset, using horizontal bars to compare values. The visualization is built with React and D3 v6, using `scaleBand` for the categorical y-axis and `scaleLinear` for the quantitative x-axis. SVG rectangles render the marks, while custom React components encapsulate the axes and data mapping. Population values are parsed from CSV and sorted by the top ten entries.
