Graphs are broken into 1GB and 6GB file chunks so that the download process does not get interrupted when downloading one large file. File chunks are created using:
"tar czpvf - ../../graph_data | split -d -b 6000M - malnet-graph"

To recombine file chunks after downloading, run:
"cat malnet-graph* | tar xzpvf -"

Once the files have been recombined, the data can be uncompressed using:
"tar -xvzf /path/to/file.tar.gz"

MalNet-Tiny contains 5000 graphs across 5 types, where each type contains 1000 graphs.
