问题
I've been trying to build a gauge using d3 and ive managed to hack up something that meets the visual requirements http://bl.ocks.org/ameyms/9140907
This is however a very very hacky solution since ive positioned the needle by trial and error and the whole thing breaks if height and width are assigned percentage values. So how do I position it?
Also, how I can make the needle rotate?
Any ideas?
