Word clouds have been added to FreeEed as an early release. To try, download the jar from here, https://s3.amazonaws.com/shmsoft/releases/freeeed-processing-1.0-SNAPSHOT-jar-with-dependencies.jar and replace the jar by the same name in your install. Then run freeeed_player.sh (.bat) as usual.
Here is an example of a word cloud and a screenshot of the Analytics menu, which features word clouds.
The word cloud is from project included with FreeEed, which is just a collection of unconnected documents, so the cloud is not very meaningful. You should get something related to your use cases and more useful.
Your feedback will be very much appreciated.
