This is a bar chart that displays the populations of ten countries, including China, India, and the United States, with each bar’s height corresponding to the population value from a CSV file. The chart is rendered as an SVG element with a width of 960 pixels and a height of 500 pixels. The visualization is built using D3 v5, specifically utilizing the `d3.select` and `d3.csv` APIs to read and parse the data, while the rendering itself is handled directly through SVG attributes.
