How to plot a decision tree (using a graphics package)

57

Is there a possibility to plot a decision tree using `Plots.jl` (or some other graphics package)? I'm using MLJ and the only means to visualize a decision tree seems to...

I've made a Pluto notebook which reads the shapes of all countries (using `Shapefile`) from [Natural Earth](https://www.naturalearthdata.com) and renders them, thus creating a world map. I've used AoG for this...

How to create an ordered bar plot?

1

I'm trying to create a bar plot which shows the population size of different regions and would like to order the bars according to population size (see: https://github.com/roland-KA/StatisticalPlotsWithJulia, the bar...

`GraphRecipes.jl` has a dependency on an old version of `AbstractTrees.jl` and thus prevents the use of the current version 0.4.2 of that package in any environment where `GraphRecipes` are used....

TreePlot doesn't respect order of subtrees

I tried to plot some binary trees with `TreePlot` and noticed that sometimes the left and right subtrees are plotted in the correct order and sometimes not. Here is a...

Add an abstract type for `AbstractTrees` to `AbstractTrees.jl`

I'm currently implementing a plot recipe for decision trees in order to be able to visualize all decision trees within the MLJ-package. The goal is a plot recipe that 1....

The AoG documentation states (https://aog.makie.org/stable/generated/visual/) that the Makie-attributes can be passed to `visual`. E.g. `visual(BarPlot)` may be enhanced with: `visual(BarPlot; width = 0.8)` to specify the width of the bars....

I've tried `Strapping.jl` on the following example: ```julia struct Person id::Int64 firstname::String lastname::String end struct Club id::Int64 name::String members::Array{Person} end StructTypes.StructType(::Type{Person}) = StructTypes.Struct() StructTypes.idproperty(::Type{Person}) = :id StructTypes.StructType(::Type{Club}) = StructTypes.Struct() StructTypes.idproperty(::Type{Club})...

Tutorial 04: `predict(..., rows = 1:3)`

In part 04 of the tutorial, in section '*The tuning wrapper*' there is a `predict` statement applied to the tuned model/machine: `predict(tuned_mach, rows = 1:3)` To me it is not...

I have to convert text files from an UTF-encoding to a ISO-8859-1-encoding. In this case not all characters can be converted to the target encoding. So, whenever `encode` encounters a...
