class of trees or graphs
Here we can see how to generate all the trees of order $n$ and is not upto isomorphism. But I dont want all trees of order $n$.
I want to know is there class of graphs which are particular typres of trees, like class of paths.
In general where I can find how to define class of complete graph, cycles, . . .
Kindly share the link for the documentation.
Thank you.
