Q1 B — CO2 per capita by country (2023), three
orderings
Q1 C — Stacked bars: CO2 per capita, country
× year (2016–2023)
Each bar = sum of the 8 yearly per-capita values
(tonnes per person over the 8 years). Sorted by the
total.
Q1 C — Grouped bars: CO2 per capita, country
× year (top 15 countries)
Same two keys, side by side. Only the top 15
countries (by 8-year total), because 50 × 8 =
400 bars did not fit.
Q2 A — Heatmap: renewable share (%) by country
× year, alphabetical rows
Q2 B — Same heatmap, rows sorted by row mean
(high to low)
Q3 A — Radial bar chart: CO2 per capita 2023,
top 12 countries
Countries placed alphabetically clockwise from the
top (same order as the default bar chart).
Q3 B — Parallel coordinates (2023, one line
per country, coloured by region)
