%description
Visualize the partitions of simple decision trees, involving one or two
predictors, on the scale of the original data. Provides an intuitive
alternative to traditional tree diagrams, by visualizing how a decision
tree divides the predictor space in a simple 2D plot alongside the
original data. The 'parttree' package supports both classification and
regression trees from 'rpart' and 'partykit', as well as trees produced by
popular frontend systems like 'tidymodels' and 'mlr3'. Visualization
methods are provided for both base R graphics and 'ggplot2'.
