This visualization is a horizontal bar chart displaying the population of the top 10 countries in the year 2000, sourced from a CSV file. The chart uses a linear scale for the population values and a band scale for the country categories, with green bars and blue tick marks. The React-based code leverages D3 version 5 modules like `scaleBand`, `scaleLinear`, and `format` to compute scales and tick formatting, rendering the chart as SVG elements.
