A bar chart displays the top ten countries by 2020 population, loaded from a CSV dataset of UN country-wise population figures. Using React for component rendering and D3 v7 utilities for data processing and scales, the visualization constructs a horizontal bar layout with a linear x-axis and a banded y-axis. The SVG output includes axis ticks and gridlines generated via `scaleLinear.ticks()`, with axis labels positioned using `scaleBand`. This example demonstrates a hybrid approach where D3 handles data binding and scaling while React manages the DOM output.
