# playdot - A simple playground for dpic and dot
A simple webservice that displays an editor for dpic- and dot-input and shows
the SVG-output or error messages below it. Allows for sharing of links to the
input.
You must install dpic from https://ece.uwaterloo.ca/~aplevich/dpic and graphviz
first before you can use godpicdot.
