Aren't tensors a sort of generalisation of matrices? How are they equivalent to graphs?

The word tensor in this context refers to a multidimensional array, not to a tensor in the mathematical sense. The computation graph is simply a representation of a sequence of arithmetic operations that you're performing on some data.
