This example shows a horizontal bar chart ranking the ten most populous countries, with population values scaled to thousands and formatted with abbreviations like "B" for billions. It uses D3 v5 within a React wrapper, reading data from a CSV file and rendering SVG elements. The chart customizes axes using `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom`, with tick formatting via `d3.format` and grid lines created by negative tick sizes.
