This interactive D3.js visualization compares 2023 country-level CO2 emissions across five socioeconomic indicators using both a radial chart and parallel coordinates. The radial chart plots CO2 per capita on the axis while the parallel coordinates view connects each country’s scaled values for population, GDP, energy consumption, and renewable energy share. Users toggle between three views: the radial layout, a standard parallel coordinate plot, and a reordered axis version. The application loads environmental and economic data from a CSV file, filtering for the specified year and numeric completeness.
