delicious Tags'n'users Wheel
Over the weekend, I posted a couple of visualisation demos that displayed the history of a URL as it has been bookmarked on delicious (delicious URL History - Hyperbolic Tree Visualisation and More Hyperbolic Tree Visualisations - delicious URL History: Users by Tag).
I also had a play with the Moowheel javacscript visualisation library that plots connections between nodes on a wheel. Once again, I used the delicious URL history to plot the users who had bookmarked a particular URL, along with the tags they used:
This representation essentially 'flattens' the hierarchy displayed using the hyperbolic tree visualisations. Both tags and usernames are plotted on the wheel. Hovering over one of the labels (user or tag) highlights the connectsions from that label (so you can see who used what tags, or what tags a particular person used).
The demo can be found at http://ouseful.open.ac.uk/moowheel_v01/demo/demo.php?url=http://www.bbc.co.uk/
The url argument identifies the URL whose delicious history you want to plot.
As with the hyperbolic tree visualisations, delicious history data is pulled into the page from delicious via a URL pipe. A small amount of javascript processing within the page puts it into the format required by the moowheel visualisation library.
