This bar chart visualizes population estimates for ten countries, ordered alphabetically along the vertical axis with horizontal bar lengths proportional to population counts. The visualization uses D3 v6 within a React framework, employing `scaleLinear` and `scaleBand` to map data values to SVG coordinates. The code loads data from a CSV file using `d3.csv`, converts population strings to numbers, and renders the chart as an SVG with axes generated by `axisLeft` and `axisBottom`. Bars are styled with a steel-blue fill via CSS.
