This gist adapts a wordcloud visualization from http://www.jasondavies.com/wordcloud/ as a Juttle view, adding transitions between batches for updates.
As a silly little showcase, the demonstration program calculates a frequency count of words from Dr Seuss' "The Cat in the Hat" (text pulled from http://paulandlizdavies.com/poems/cat.htm) by splitting the words from each page into separate points, then counting the words by frequency and showing them in the wordcloud and a barchart.
