For those who die a little inside every time they see a word cloud: shield your eyes. For the less dramatic, Jason Davies, in his latest D3 bucket-o-fun, created an interactive word cloud that lets you search on Twitter, Wikipedia, or your own URL. Change one of the parameters such as angle, number of words, and scale, and oh yes, the words move. Once you're satisfied with your creation, you can export it as a PNG or SVG.
Don't worry. Davies does recognize the non-analytical nature of word clouds at the end of his explanation.
The code is also available on GitHub in case you want to have a go with it.
[Word Cloud | Thanks, Jason]
