This horizontal bar chart displays the population of ten countries for the year 2000, sourced from a CSV file via `d3.csv`. The visualization uses React to render an SVG, with `d3.scaleBand` for the categorical y-axis and `d3.scaleLinear` for the population x-axis, formatted using `d3.format`. The chart highlights the `d3.axisBottom` and `d3.axisLeft` components, with tooltips showing values on hover.
