This visualization uses a Vega-Lite API to render an interactive line chart of CO2 emissions over time, with three distinct types compared via colored lines. The chart encodes Year on the x-axis, emission amount on the y-axis, and type as color, with tooltips showing year values. Data from a CSV file is loaded via d3.csv, and the vega-lite-api library, combined with vega-tooltip for hover interactions, generates the SVG output. The visualization fills the entire browser window and uses custom axis styling.
