This bar chart displays the top 15 CO₂-emitting countries in 2020, with bars scaled linearly to show each nation’s emissions in megatonnes. The view uses an SVG rendered by D3 v7, loading tab-separated data via `d3.tsv` from a public GitHub gist. Bars are drawn with `scaleBand` and `scaleLinear`, while rotated tick labels on the `axisBottom` improve readability of country names. The chart includes a bold title and axis labels for country and emissions, all created using standard D3 selection and join methods.
