Hi, I was wondering what method would work best for building the graph dynamically for this module. I have tried varying things, and it hasn't worked. Specifically, how do you replace the hard coded node information in the example with passing in a variable that contains a dynamically built list of nodes? I have tried building both arrays and scalars dynamically, e.g. $pr_nodes, or @pr_nodes, and then calling

or

and they both fail. Any help would be appreciated. Thanks.
