This example presents two side-by-side bar charts ranking the top ten countries by GDP per capita and by gross primary education enrollment. The charts use D3.js version 6 to load CSV data from remote GitHub sources and render scalable vector graphics (SVG). Each bar chart uses `d3.scaleBand` for the x-axis and `d3.scaleLinear` for the y-axis, with `d3.axisBottom` and `d3.axisLeft` for ticks. Interactive tooltips appear on bar mouseover, showing the country name and the corresponding metric value.
