This bar chart displays the population of ten countries, from China at over 1.4 billion down to Mexico at 130 million. Built with React and D3 v5, it renders as an SVG using `scaleLinear` for the x-axis and `scaleBand` for the y-axis, with axes added via `axisBottom` and `axisLeft`. Population data is loaded from a CSV file and converted to numbers before rendering, with bars colored green and a styled path for the axes.
