This scatterplot visualizes the relationship between GDP (x-axis) and population (y-axis) for various countries. Each circle represents a country, with tooltips revealing the country name, GDP, population, and calculated GDP per capita. Built with React and D3 v7, the visualization uses `d3.csv` to load data from a GitHub repository, `d3.scaleLinear` for axis scaling, and `d3.axisLeft` and `d3.axisBottom` for tick labels. It is rendered as an SVG, with data formatted using a custom `numMaker` utility that abbreviates large numbers into billions and millions.
