Documentation: How to add properties to graph

[masipila]

Hi,

I need to change the rankdir of the graph from the default TB (top-to-bottom) to LR (left-right) but I haven't figured out how to add attributes to the graph itself.

The output that I'm looking for is this:
digraph G { graph [rankdir="LR"] "Hello" "World" "Hello"->"World" }
The example on the readme shows how to add attributes to the elements of the graph but not how to add them to the graph itself. The following didn't work:
$graph = new Graph(); $graph->setAttribute('graphviz.rankdir', 'LR');
Cheers,
Markus

Read the source, Luke :)

$graph = new Graph(); $graph->setAttribute('graphviz.graph.rankdir', 'LR');

Thanks for posting the answer to your own question! :)

I'll make sure this gets added to the readme once we tackle #2 👍
