This horizontal bar chart displays the population of ten countries in the year 2000, with each bar’s length proportional to its population value. The visualization uses a linear x-scale for population and a categorical y-scale for country names, with tooltips revealing the exact formatted population figures. Built with React and D3 v5, the code employs `scaleBand` and `scaleLinear` for scaling, `csv` for data loading from a remote GitHub source, and renders the chart as an SVG. The chart includes labeled axes for population and country, with the y-axis ordered by the country values.
