Hi, when running a simple script like this: ```julia using GraphViz using FileIO function foo() g = dot""" digraph graphname { a -> b -> c; b -> d; }...

Add engine attribute to Graph, and default to 'dot' layout

3

On #38, we noticed that some position-related attributes are not working (e.g., rankdir). Apparently, the code is using the layout "neato", and the layout that we want to use is...

Does not seem to handle certain position related attributes

6

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. ```dot digraph graphname { rankdir="BT"; overlap=false;...

Possible thread safety issue with `active_devices`

Add basic exception handling

2

Consider a dot literal: ``` dot""" graph G{ a -> b } """ ``` Currently this will give an assertion exception when layout discovers the graph.handle is C_NULL. Actually Graphviz...

The issue is described here: JuliaLang/julia#56150 #45 ReactiveBayes/GraphPPL.jl/pull/268 These changes fixed the issue for me. However, I need the cairo_render only, so, most likely, the other functions should be fixed...

Wrong conversion of String to C String?

3

I noticed [this line of code](https://github.com/JuliaGraphs/GraphViz.jl/blob/25024715457db3321b477ccc17c08eab6eac37e0/src/cairo.jl#L49) in GraphViz.jl package, but later on a String object being used [here](https://github.com/JuliaGraphs/GraphViz.jl/blob/25024715457db3321b477ccc17c08eab6eac37e0/src/cairo.jl#L82) (note the format="julia:cairo"). It doesn't seem right? The function expects C string,...
