How to import external big data into DGL?

All DGL demos are relied on a well formatted internal data. I am wondering if there are any codes showing how to create exactly the same formatted data as ACM.mat from the raw dataset ? I know DGL introduction shows briefly that DGL graph can be created from edge list or networkx graph. But none of them is big data from scipy.sparse.csr matrix format.

You can construct a DGLGraph from scipy.sparse.csr matrix format, see the documentation.
