I am giving a presentation next week on NoSQL and as part of that I wanted to create a Word Map, similar to the ones I have seen in the Guardian over the years. After searching a little, I came across the following two sites which do an excellent job of this. Both of them allow a number of options to customise the output and I think are very cool!
The first one is Jason Davies , World Cloud that is open source and you can integrate online searches, twitter searches, etc. The word map below is an example output when I search “bahree” on twitter .
