This chart displays the populations of 10 countries in the year 2000, sorted from largest to smallest in a bar chart. The visualization uses D3.v7 with SVG rendering, employing `d3.scaleBand` for the categorical x-axis and `d3.scaleLinear` for the population y-axis, with values formatted in billions. The data is loaded from a CSV file via the `useData` module and rendered through custom `AxisBottom`, `AxisLeft`, and `Marks` components.
