This line chart visualizes carbon emissions in Rio from 2010 to 2015, drawing on a CSV dataset. Using D3 v5, it encodes time on the x-axis with `d3.scaleTime` and emission values on the y-axis with `d3.scaleLinear`. The SVG rendering includes axes, grid lines, labels, and a purple line path generated via `d3.line`. Data is loaded asynchronously with `d3.csv` from a GitHub gist.
