A bar chart displays the GDP of ten countries, with countries on the y-axis and GDP values on the x-axis. The chart uses d3.scaleLinear for the x-scale and d3.scalePoint for the y-scale, rendering circles instead of bars via SVG. Axes are generated with d3.axisLeft and d3.axisBottom, while GDP labels are formatted using d3.format with a custom tick format. Data is loaded from a CSV file using d3.csv, and the visualization is styled with CSS for tick text and axis labels.
