This bar chart displays the top ten countries by 2020 population using a horizontal layout. Built with React and D3 v5, the visualization uses SVG for rendering and scales from `d3.scaleBand` and `d3.scaleLinear` to position bars and axes. Data is loaded asynchronously from a CSV file via `d3.csv` in a custom `useData` hook. Custom React components handle the axes and marks, with the y-axis showing country names and the x-axis representing population values.
