This reminds me of the graphology metrics we use to compute sizing - here's the sizing story

Maybe we could add a getNodes() callback or something that you can use to get a list of nodes and their "rankings" without affecting sizing? We'd prob also need to add somethin like a ranking prop, similar to sizingType

e.g.

const nodes = graphRef.current.getNodes();

<GraphCanvas ref={graphRef} ranking="centrality"/>
