This animated scatterplot shows GDP per capita versus CO₂ per capita over time, with points colored by region and a play/pause button to step through yearly frames. It loads CSV data via `d3.csv`, maps numeric columns, and uses `d3.scaleLinear` for axes and `d3.scaleOrdinal` with the Tableau10 scheme for region colors. Each frame filters rows by year and transitions circle positions using `transition().duration(700)`, updating a status line with the current year.
