A few months ago I learned d3.js and made myself an interactive site logo for myself with it. It's an awesome library.

Check out the logo (try clicking it and dragging the letters) and tutorial at http://tullo.ch/2012/making-the-site-logo/.

Your logo doesn't work. I'm using the latest Firefox on a Mac. Error: strengths is undefined.

Hmm strange, just tested then and works on my end with Chrome 18 and Firefox 12.0 on OS X.

I'm on Chrome 20 on OS X and I got this error:

    Cannot read property '0' of undefined      d3.v2.js:5166

I got this too. It's reproduceable for me if I click on any of the nodes before the page is ready for it, and once this happens I can't use it at all. But if I wait a second or two before doing this it works fine. Using latest chrome.

Same as oulipian, I got some error about 0 being undefined.

Also, if you are planning on doing a spring-mass simulation, it's much better to use arbor.js which has background thread support (and is non-blocking)
