This bar chart displays population estimates for the year 2000 across ten selected countries, using horizontal bars where length encodes magnitude. The chart is rendered as an SVG via React, with scales built by `d3.scaleBand` and `d3.scaleLinear`. The `Marks` component draws each `<rect>` with a `<title>` tooltip; axes are generated by custom `AxisBottom` and `AxisLeft` components. The data is loaded from a CSV file using `d3.csv`, applying a custom row parsing function that multiplies the raw value by 1000 before slicing the top ten entries.
