Code Issues Proposed changes

Fixes syntax error in older versions of graphviz.

Browse Source 
Older versions of graphviz (tested on version 2.26.3 (20100126.1600))
complains when an attribute is empty without quotes. [label=] fails but
[label=""] works, so the quote_if_necessary function has been updated to
accommodate this.
