See the following example.

```julia
julia> using AbstractTrees

julia> function AbstractTrees.children(i::Integer)
           if i <= 3
               return i + 1, i + 2
           end 
           return ()
       end
julia> print_tree(1)

├─ 2
│ ├─ 3
│ │ ├─ 4
│ │ └─ 5
│ └─ 4
└─ 3
   ├─ 4
   └─ 5

```

Does there exist any package or utility method to print a tree in its _normal_ looking? That is, I want the form below

Perhaps try [GitHub - JuliaGraphs/GraphPlot.jl: Graph visualization for Julia.](https://github.com/JuliaGraphs/GraphPlot.jl). Probably have to tweak settings to get it to look the way you want.

Thanks. I believe `Graphviz` is also a good choice for printing into a file. However, I want to print the above tree into the terminal.
