Lately, I see on customers farm topologies drawn by hand, with strange icons etc
The truth must be told, my point is the most elegant way to draw those topologies is via Visio and the New Office Stencils. For instance, the following one extracted from a Product group white paper
BTW, these stencils are not only limited to SharePoint any product related to New Office has its own icon like Lync v.g.
In order to have them you have to download them from
and set them up following the next guide
I hope it will like you.
