A responsive scatter plot visualizes the relationship between population and GDP across countries, coloring each point by region and providing hover tooltips with country details. It uses d3.csv to load an external dataset, then d3.scaleLinear for both axes, d3.axisBottom and d3.axisLeft for ticks, and a d3.scaleOrdinal with d3.schemeCategory10 for regional colors. The SVG output includes labeled axes, a title, and a legend, with all elements rendered via standard D3 data joins.
