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](https://stackoverflow.com/questions/4070150/data-visualisation1.) so you can take a deeper look to understand my question better.

Answer: 
Maybe this [one](https://ux.stackexchange.com/questions/953/how-to-display-the-hierarchical-data-closed) 

**ADDED:**

and use it with combination of [Topic Map](https://ux.stackexchange.com/questions/1056/how-to-use-topic-maps) to find out *associations*, *occurrences*(number of occurrences to size "circle") between **topics** (entities).
If you are trying to "visualize" relationships between 1 or more things you may find a tool like [this](http://yuml.me/diagram/scruffy/class/samples) 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.
