TreeRecipe.jl
A Plot recipe for plotting (decision) trees.
A plot recipe (based on RecipeBase.jl) to create a graphical representation of a tree.
The recipe has originally been designed to plot decision trees, but it is able to plot all sort
of trees which conform to the following rules:
- The tree must be wrapped in an
AbstractTrees-interface. I.e. it has- to be a subtype of
AbstractTrees.AbstractNode{T} - implement
AbstractTrees.children() - implement
AbstractTrees.printnode()
- to be a subtype of
See DecisionTree.jl/abstract_trees.jl for
an exemplary implementation of the concept. In addition there are examples in the examples-folder which show how the recipe can be applied to plot decision trees from the DecisionTree.jl-package as well as from the BetaML.jl-package.
This approach taken by TreeRecipe ensures that a tree implementation can be plotted without having any dependencies to a graphics package and it ensures furthermore, that the recipe is independent of the implementation details of the tree.
For more information have a look at the article "If things are not ready to use" in Towards Data Science where the basic ideas are explained.
And here you get an impression on how a plot of a decision tree might look like (in this case a DecsionTree with the Iris dataset):
