This example displays a horizontal bar chart showing the 2020 populations of the top 30 most populous countries, sorted in descending order. It uses SVG rendering with a React front end, and builds the visualization with D3 version 5 scales, including `scaleBand` for the categorical country axis and `scaleLinear` for the population axis. The data is loaded from `Activity6_Population.csv` using D3's `csv` function.
