How have you used or intend on using this resource?

I've had a look through the examples which are good for generating ideas for how to present data visually, though a lot of the visualisations are a bit complex so I'd probably be using these as a starting point for ideas and then searching elsewhere for guidance on how to do a simpler version.

I will probably go back and have a closer look at the word tree and word cloud generators though as these are simple to use and generate visually appealing generations. 

Why would you recommend it to other people?

As above, for inspiration primarily and the use of the text visualisation generators. Though, alongside this I'd probably also share some guidance on appropriate usage on the use of word clouds, such as the BetterEvaluation option page on Word Clouds (written by Stephanie Evergreen) which offers advice on when word clouds are appropriate, and this article on why word clouds [can be] considered harmful. There's also guidance on how to and when to use word trees.
