This bar chart displays the populations of ten countries, with bars extending horizontally from a left-aligned axis. The visualization uses D3.js v5 within a React framework to load CSV data and render SVG elements, employing `d3.scaleLinear` and `d3.scaleBand` for proportional scaling. It generates left and bottom axes via `d3.axisLeft` and `d3.axisBottom`, and appends rectangles through a data join to encode population values.
