Create a subgraph for each VPC #1
Description
Maybe each VPC can be put into a cluster/subgraph https://graphviz.gitlab.io/_pages/Gallery/directed/cluster.html
This seems doable with push_subgraph and pop_subgraph https://metacpan.org/pod/GraphViz2#push_subgraph(%5Bname-=%3E-$name,-edge-=%3E-%7B...%7D,-graph-=%3E-%7B...%7D,-node-=%3E-%7B...%7D,-subgraph-=%3E-%7B...%7D%5D)
