How to show related data together in one diagram?

Question

Let us have the following three sets of information

---

---

Now I want to combine all of this data and show it all together. Telling it like a story. Giving inter-relations. Showing similarities in terms, concepts etc. to get the following (Note that in the diagram below, the colored relations may not be exact, they are merely indicative of a node of information)

Question: Is there a good way to do it. Also, Is there a tool available for doing this?

I hope this make the question much more clear. :)

I have posted this question originally on stackoverflow here so you can take a deeper look to understand my question better.

Answer 1

Maybe this one

ADDED:

and use it with combination of Topic Map to find out associations, occurrences(number of occurrences to size "circle") between topics (entities).

Answer 2

If you are trying to "visualize" relationships between 1 or more things you may find a tool like this very handy. Not only does it let you visually build a picture with simple text, but it handles many of the "odd" scenarios that might otherwise be hard to indicate.
