This example presents four linked D3.js visualizations of climate-related data from a CSV file: a pie chart of CO2 emissions for 1950, a line chart of cumulative CO2 emissions over time, a scatter plot of global mean sea level changes, and an area chart of per-capita CO2 emissions. Using d3.csv and d3.autoType to load and parse the data, the code builds each chart with d3.pie, d3.arc, d3.line, d3.area, and d3.scaleLinear, rendering SVG elements directly in the DOM.
