Yes, people of the internet, LastGraph has returned. After over two weeks of beta testing and bugfixing, it's finally in a useable state, and so I'm pushing it out to lastgraph.aeracode.org as I type this. If it doesn't work for you yet, wait for the DNS change to propagate.
LastGraph is still undergoing rewriting after the beta showed up some lovely bugs (including inverted labels and labels everywhere they shouldn't be). I'm working on it over the weekend, after my week was overtaken by the sheer mass of activity involved with university and Fresher's Week (I find it strangely ironic that it's actually more timeconsuming this year, when I'm <u>not</u> a fresher).
