In your stylesheet, you can define the style according to degree.

e.g.:

node[[degree = 0]] { /* ... */ }
node[[degree >= 1]][[degree <= 3]] { /* ... */ }
node[[degree >= 4]] { /* ... */ }

Refer to the data selectors and use the [[metadata]] double square brackets.

If you need more precision (i.e. on the JS code level rather than the stylesheet level):

If your graph is static, you could add a degree data attribute to each node and use a mapper in your stylesheet with that attribute. If your graph is dynamic, you could use the same approach but update the degree attribute as the graph is modified.
