Change pyviz node size when label is inside

Question

In pyvis, 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 the shape is circle, then the size parameter is not taken into account. If the shape is dot, then the size parameter is taken into account. Is there a way that a node shaped like, e.g. a circle, can have the label inside and also have its size changed?
