This bar chart shows the top 10 most populated countries, ranked by their GDP in USD. The visualization uses d3.csv to load world data from a remote GitHub-hosted CSV file, then sorts the data in descending order and selects the first ten entries. Rectangular bars are rendered in SVG, with d3.scaleBand and d3.scaleLinear mapping countries and GDP values to x and y positions. The code adds rotated x-axis labels for readability and applies d3.axisBottom and d3.axisLeft for the chart's axes.
