Voyant has released version 2 of its textual analyzer and visualizer: http://voyant-tools.org/ (link is also in ‘Tools’). It has a cleaner interface and seems -at least during my first testing – quicker. In the top left-hand tool interface where the word cloud appears, you can switch views: between word cloud (‘cirrus’), raw word counts (‘terms’), and word-frequency links (‘Links’).

NB: see also their new ‘Guides’ section!
