Is it possible to have a label inside a node as well as a label below it?

Just looking for a way to put a identifier inside a node with a description below the node.
Something like this:

You can create your own custom node renderer using HTML canvas primitives. For your example, you would output a filled circle, and 2 difference pieces of text, presumably the label and another custom node property. I believe the vis examples show how to do this.

Briefly, here you could do the following JavaScript pseudo-code:

function drawNodeTwoLabels( { ctx, id, x, y, state: { selected, hover }, style } ) {
}

node1.ctxRenderer= drawNodeTwoLabels;

In the function you set up the stroke style and width, and fill style and draw the arc. You then draw the 2 labels positioned relative to the x,y you are passed, and the size of node you drew.
