I’ve just come from one of the most fantastic visual research tools I have ever come across. Touchgraph gives you visually in one page, what Google, Amazon and Facebook cannot deliver in pages of text. A clear understanding of how websites, books and people are related based on your search criteria at a glance. The TouchGraph product can also be customized to interact with your databases to reveal patterns in your data that text and traditional graphical tools cannot capture or represent. I would love to see this hooked up to my corporate data warehouse.
This is a brilliant tool and I find it highly addictive. We need more graphical tools like this to help us to break out of the constraints of columns, rows, lines, bars and pies.
It would be nice to see WordPress integrate this into viewing their tags and search.
