I have no idea how a mitab file looks like, but chances are that
you'll have to convert it into a format supported by igraph first, and
then use read_graph() in R or Graph.Read() in Python.

igraph is primarily a library for the _analysis_ of networks and not a
plotting / discovery tool. You might have more luck with using
Cytoscape or Gephi if you are primarily interested in plotting and
browsing. Cytoscape might even support the mitab format natively
because it is specifically tailored towards bioinformatics
applications.

All the best,
