Run an external command on the specified DotRepr. Remember to use hSetBinaryMode on the Handle for the output function if necessary. If the command was unsuccessful, then a GraphvizException is thrown. For performance reasons, a temporary file is used to store the generated Dot code. As such, this is only suitable for local commands.
