Login to every device, and find neighbors using CDP (or similar methods), and draw every single one, and it's connected devices. Login to every one of those and do the same. Go on and on without a break, until you have a full map (don't bother with CEs, or omit other devices too far from core that are not too important, but draw at least one example, so you have visual representation on how the end circuit looks).
Then, press CTRL+K on every device and enter telnet://HOSTNAME-OF-THE-DEVICE so, now you can simply click on visio diagram, and your default telnet app will start telnetting to the device directly.
This is the best way for me to create the first step.
in addition to previous poster (great answer by the way !!).
