Feature Impacts on Target
Overall impact on features w/o consideration for other features
Standalone effect on target
Green bar

Most likely to yield predictive value
many will contain same information
Overall impact adjusted for other features
Each feature adjusted for the other features in the model
scaled from 1-100
