Change node size when label is inside

[angoodkind]

If a node has a label inside of it, then the node's size is determined by the label text inside of it. For example, if shape = 'circle', then the size parameter is not taken into account. If shape = 'dot', then the size parameter is taken into account, but the label's text is below the node.

Is there a way that a node shaped like, e.g. a circle, can have the label inside and also have its size changed?
