A bar chart displays population totals for ten countries, from China’s 1.4 million to Mexico’s 0.13 million, using a familiar categorical comparison. The example loads the CSV data with the `d3.csv` function inside a React hook, then renders the chart with the Victory library’s `VictoryBar` and `VictoryChart` components. The code explicitly sets large tick-label font sizes and chart dimensions via the `style` and `padding` props.
