This visualization shows the population of the top 10 countries in 2020 as a horizontal bar chart, with all bars aligned to the left and sorted by country name. The application loads the data from a CSV file using D3’s `csv` utility, then renders the SVG with React components for the axes and marks. The y-axis uses `scaleBand` to position categorical labels, while the x-axis uses `scaleLinear` for the numeric population values. Each bar is drawn as a `<rect>` via the `Marks` component, with size determined by the population value.
