C#: Tumblr Blog Description Top Word Frequency List Visualization

Leave a reply

Browsing reddit; I found a parsed dataset from Tublr. Link Here.
I used code from an older post to obtain a list of unique words, and their frequencies.
Next, I used a default TermCloud – Sample from GoogleCharts’s Additional Charts Gallery, to generate this image in a web browser.

Tublr blog description: words with a frequency greater than 5,000, ordered by most to least frequent.
