A horizontal bar chart displays the populations of ten countries for the year 2000, sorted by country name. The visualization uses React with D3 v5, employing d3.scaleBand and d3.scaleLinear to encode data from a CSV file, with SVG rects drawn for each bar. Gray bars are annotated with axis labels and formatted tick values using d3.format, while hover tooltips show precise population figures via SVG title elements.
