Let's say I have a table of words, and each word has a "related words" column. In practice, this would probably be two tables with a one-to-many relationship, as each word can have more than one "related words" columns, but for simplicity, say it looks like this:

Word      | Related words
------------------------------------------------------
integer   | fraction, entire, integral ...
entire    | entirely, integer ...
fraction  | fractious, fractional, integer ...
fractious | fraction, -ous ...
-ous      | ambidextrous, advantageous, atrocious ...

And so on. I want to create a graph which shows how all of the words interlink, based on the relationships I've described in this table.

I've found an online tool which does exactly what I want, and used it to produce an example:

Is there a Python module which can be used to produce this sort of graph? I'm not too sure what this kind of graph is called, so I'm not sure how to research this question. I'd appreciate any pointers, or advice on how I can clarify and improve this question if needed.

NetworkX is a Python package for the creation, manipulation of complex graph networks. It also supports interfacing with Matplotlib package for drawing the graphs.
