how can I force wolfram alpha to interpret uploaded dot files as a graph? If I use terms as “vertex count” or “basic properties”, it will be interpreted as a “mathematical definition”.
The dot files are relatively large, but the internal structure itself isn’t complex. A few nodes and edges can be parsed without any problems; with a few hundred nodes, I will get the described behaviour.
I’m afraid the most likely answer is that the file is too big and Wolfram|Alpha won’t work with it.
If you want to work with larger files, your best bet is to use Mathematica online:
