Need a quick diagram for the paper you’re working on? Instead of this:
\begin{figure} \vspace{0.5in} Remember to put a diagram here! \vspace{0.5in} \caption{The to-be-written awesome caption will go here.} \label{fig:now-its-all-clear} \end{figure} what if you could quickly turn a whiteboard sketch into a diagram suitable for use as a draft — and maybe even for use in a camera-ready, depending upon your drawing skills — in your paper?
