Since 2004 this site had been serving up SU needle graphs. In October of 2017 the host it used closed its doors. The pain of porting 12 year old code to another host wasn't something I had the energy for.
However, it turns out that the graphs were quite popular— far more popular than I gave them credit for. So, due to popular demand, I've decided that I had better keep this place going.
Please bear with me whilst I port the code across to something a bit more modern.
