This interactive visualization, built with React and D3 v7, presents multiple arrangements of a country-level dataset focused on CO2 emissions per capita. Users select from nine views, including alphabetically and value-ordered bar charts, stacked and grouped bar charts, reorderable heatmaps, a donut chart, and parallel coordinate plots, all rendering as SVG. The code leverages D3 scales like `d3.scaleBand` and `d3.scaleLinear`, color schemes from `d3.schemeTableau10`, and the `d3.rollup` helper to aggregate data by country and year for the matrix and parallel views. A shared dataset loaded from CSV drives all chart types.
