This bar chart displays the population of 20 countries in 2010, with horizontal bars sorted alphabetically by country name and scaled linearly by population. The visualization uses React alongside D3 v5’s `scaleBand`, `scaleLinear`, and `csv` for data loading, rendering SVG rectangles through the custom `Marks` component. Axes are generated by `AxisBottom` and `AxisLeft`, with formatted tick labels using `format('.2s')` and a tooltip via `<title>`. Tick lines are styled blue and bars green, with data sourced from a remote CSV file.
