This visualization presents meticulously curated data on CO2 emissions per capita and total CO2 emissions for 30 countries, sourced from the World Bank.

The visual alphabet of the presentation employs curves, sizes, orientation, length, line thickness, color, and opacity to effectively communicate the nuanced information on topic of interest. Smooth curves depict trends over time, and the size of circles is proportional to total emissions. Line thickness and orientation convey magnitudes and changes, and annotations provide additional insights.

This approach from data cleaning to visualization design, ensures that the audience is presented with a clear, accurate, and insightful portrayal of topic of interest.
