This chart displays the population figures for the top 10 countries in the year 2000, using a horizontal bar chart where each bar’s length corresponds to its population value. Built with React and D3 v5, the visualization uses `scaleBand` for the categorical country axis and `scaleLinear` for the continuous population axis, rendered as SVG rectangles. The data is fetched from a CSV file via `d3.csv`, and tooltips show formatted population values using `d3.format`. The code defines custom `AxisBottom`, `AxisLeft`, and `Marks` components to manage the chart’s layout.
