Extend basics tutorial concerning draw_hypergraph

I can't seem to control the node size on an individual basis in the draw_hypergraph function. 

Ideally, I would be able to use a dictionary with the node names as key and the node size as value. 

I have tried constructing a np.array in all shapes and sizes that holds this information but I always get: "ValueError: s must be a scalar, or float array-like with the same size as x and y".
