Dynamic Graphs

If you click on the image before it will bring up an applet with a map of my local blog space. Navigate mode allows you to set a blog (by clicking on it) as the center, then you can shrink and expand the map. Going to edit mode makes the nodes clickable and enables the ability to click the various blogs.

Feedback is welcome - I have a few ideas about how to make it more interesting and relevant.

Fun with maps

after my last exploration with mapping blog relationships I moved over to using a Java based library Touchgraph that allowed a more dynamic look at the relationships between the blogs I link to and those that link to them. If anyone has read the book "The Tipping Point" there is a discussion about the various types of people that cause the formation of social groups. I think mapping how blogs relate to one another can illustrate some of the points the author (Malcolm Gladwell) makes. I need to re-read the blog and probably re-read linked to before I can draw any conclusions. I will admit to being fascinated with the entire investigation.

Here is my most recent map of the links around my blog. It is a static image generated from a Java Application. If I get sometime in the next few weeks I will turn it into an applet that will allow users to browse and manipulate the map. Each node expands into the next level down. I have not gone beyond that - need to do some more work on my crawler to increase speed and reduce memory consumption.
