Lately, I am getting very interested in data visualization and text mining. Just got the evaluation version of Tibco Spotfire and I would have to say this - it rocks! Beautiful high-quality visualizations, and a good number of features.
Was also playing around with the Keyword Tree from Juice Analytics. A brief description of this tool:
What search words and phrases are driving traffic to my site?
In the word tree visualization, you'll see a frequently used search term at the center. To the right and left, it shows the search terms that are most often used in combination with that word. The words are sized by their frequency of use and colored by bounce rate (or 0% new visitors or average time on site).
I then linked it to my Google Analytics account, and to this blog and here's what I got. Simply BEAUTIFUL!
