Data visualization examples

Here are a few data visualization examples that we practiced in class. These exercises helped us explore different chart types, storytelling techniques, and ways to present complex information more clearly and effectively.

Chart: General Government Debt (% of GDP, 2020)

The chart below, sourced from the OECD, illustrates the percentage of general government debt as a share of GDP for various countries in 2020.
Japan and Italy show the highest debt levels (over 150% of GDP), while countries such as Estonia, Chile, and Türkiye have relatively low debt ratios.
The United States and Canada fall near the middle, indicating moderate debt levels compared to other major economies.
