# 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 first install 

   * dpic from https://ece.uwaterloo.ca/~aplevich/dpic and 
   * graphviz from https://graphviz.org

before you can use playdot properly.
