This scatter plot shows the relationship between GDP per capita (in billions) and life expectancy for countries in 2015, sourced from a GitHub-hosted GDP dataset. It uses d3.csv to load the data, scales the GDP axis logarithmically via d3.scaleLog, and colors points using d3.scaleOrdinal with d3.schemeCategory10. SVG circles are rendered with D3's data join, and hover interactions display a tooltip showing country name, GDP, and life expectancy. The axes are labeled using d3.axisBottom and d3.axisLeft.
