A little context
When to use a correlation matrix.
Explore the strength and direction of linear relationships between numeric variables. The scale runs from −1 to +1.
A design thought
Use a diverging palette centered on zero. Color indicates direction and strength, rather than proving one variable causes another.
Good question
What do the colors mean?
The two ends of the palette represent negative and positive correlations. The neutral center represents values near zero. Correlation describes association, not causation.
