The strongest 2D relationships
Ranked by normalized mutual information
NMI ranges from 0 to 1 and detects general dependence after binning continuous fields, including nonlinear relationships. Continuous pairs use a LOWESS trend; coded fields use boxplots or a count heatmap because their numeric codes are categories, not measurements.
