Edges
In a graph object, you can create edges using the edge
method
Creating an edge
The method edge
allows the creation of an edge with any number of node
identifiers:
$graph = new Graphviz\Digraph();
$graph->set('rankdir', 'LR');
$graph->edge(['foo', 'bar', 'baz']);
Edge attributes
You can pass attributes to your edge by providing a second argument with an array associating names with values:
$graph = new Graphviz\Digraph();
$graph->edge(['foo', 'bar'], [
'style' => 'dashed',
'color' => 'red',
]);
Targeting a port identifier
If you have created a port identifier inside a record, you can make your edge target this port by providing an array instead of a string.
$graph = new Graphviz\Digraph();
$graph->node('week', [
'shape' => 'record',
'label' => 'Monday|Tuesday|<wed> Wednesday|Thursday|Friday',
]);
$graph->node('people', [
'shape' => 'record',
'label' => 'Alice|<bob> Bob|Charlie',
]);
$graph->edge([
['week', 'wed'],
['people', 'bob'],
]);
