This example shows a bar graph of country populations, with blue bars sorted by the order of the data in the CSV file. The chart uses D3 v7’s `csv` method to load the data, then `scaleLinear` and `scaleBand` to map population values to bar heights and positions. Data is parsed by converting population strings to numbers before rendering, and bars are appended to an SVG container. The visualization is part of a React starter template, though this simple version relies on plain HTML and JavaScript.
