Exploring R² and regression variance with Euler/Venn diagrams

This article explains the R² statistic in regression analysis using intuitive Euler and Venn diagrams. It demonstrates how to visualize the proportion of variance explained by a model with R code, using the Gapminder dataset as an example. The content covers interpreting R², addresses common misconceptions about low R² values, and provides a technical guide for data visualization in statistics.
