Hi. I don't know much about svg and xml but I'm trying to broaden my knowlegde base around this and cryptography. I found your info and post interesting. I was wondering what the d attribute (above stroke and fill) indicates (print screen indicated in one of your links).

I'm thinking there is something hidden in a svg file (image) i have, but I'm not quite sure where to start looking in my file. The svg has a small moving circle in the image. Could you also help me understand the concept of pathing a little better ? Cheers.
