This bar chart displays the population of ten countries, ranked from largest to smallest, using a vertical bar for each nation. It reads the population data from a local CSV file and renders the visualization as an SVG element. The chart uses D3.js v5 to parse the CSV and scale the bar heights proportionally to population values, with the country names and population figures shown as labels. The data source is the included data.csv file, and the visualization is generated through D3's selection and scaling methods.
