Does not seem to handle certain position related attributes

[Binary-Eater]

Examples include attributes like rankdir.

Versions of involved components used

• Julia v1.6.3
• GraphViz.jl v0.2.0
• IJulia v1.23.2

Snippet for replicating the problem.

digraph graphname {
rankdir="BT";
overlap=false;
     a [shape="box",URL="https://www.google.com",label="Game",target="_blank"];
     b [shape="box",URL="https://www.google.com"];
     a -> b [minlen=10,taillabel = "taillabel"];
 }

What is seen in the local jupyter notebook

What is see when using graphviz to generate a PNG from the same dot snippet

First of all, thank you for this package!

I also observe that there is a problem with rankdir.

digraph so 
{
   rankdir = LR;
   A -> B -> C -> D;
}

Does not work as expected (at least under Pluto)

Expected result:

Result under pluto.jl:

Same here. Could it be the version of graphviz?

Hi! I also experience this issue in Pluto with GraphViz 7.0.2. Does anyone find a way to solve this or diagnose where the issue comes from?

[abelsiqueira]

I have created a pull request that should fix this. Can you check with ] add https://github.com/abelsiqueira/GraphViz.jl#38-add-engine-attribute. I don't know how to do add custom pkgs on Pluto.

@abelsiqueira
Thanks, I have tested it, on my side it works

To reproduce:

under bash
mkdir /tmp/test_pluto
Start Julia and ] to reach ** Pkg** mode

activate "/tmp/test_pluto"
add Pluto
add https://github.com/abelsiqueira/GraphViz.jl#38-add-engine-attribute

switch back to Julia mode
using Pluto; Pluto.run()

Then under Pluto

• Cell 1

begin
	import Pkg
	Pkg.activate("/tmp/test_pluto")
	Pkg.status("GraphViz")
end

• Cell 2
  using GraphViz
• Cell 3

dot"""
digraph so 
{
   rankdir = LR;
   A -> B -> C -> D;
}
"""

Calling GraphViz.layout!(g, engine = "dot") worked for me:

using GraphViz

g = dot"""
digraph so 
{
   rankdir = LR;
   A -> B -> C -> D;
}
""";

GraphViz.layout!(g, engine = "dot")

g
