This example shows a horizontal bar chart comparing the 2020 population of 30 countries. The chart uses D3.js v5 scales to map country names and population values to the SVG canvas, with each bar's length proportional to its population. The bars are rendered as SVG rectangles, and hovering over a bar displays its formatted population value in a tooltip. The React application loads the data from a remote CSV file and uses D3's `scaleBand` and `scaleLinear` for positioning, with custom axis components for the bottom and left edges.
