[FEATURE] Implement HTML-Like labels for Graphviz DOT generation #27

Quick and useful feature request https://www.graphviz.org/doc/info/shapes.html#html https://www.graphviz.org/pdf/dotguide.pdf

Graphviz supports HTML in labels, but needs to be escaped with < and > instead of quotes. I suggest extending the DotEscapers helper class in order to support html like labels and adding a property to the GraphvizVertex class named something like "IsHtmlLabel" to enable the feature Capture

Hello @ExusAltimus! This seems to indeed be a nice improvement. Do you have any start of work on the subject? I can try to have a look otherwise.

KeRNeLith commented 3 years ago

@ExusAltimus I prepared a branch for the feature. You can have a look at the html_label_graphviz branch, and feel free to give me feedback. Then I will plan to merge it to the master branch.

EDIT: Here is a temporary package to test the feature.
