Create Visuals & Diagrams with Graphviz (Dot Language)

Learn how to create visually appealing diagrams and flowcharts with Graphviz.

Graphviz is a free tool for creating visual diagrams, ranging from simple entity-relationship diagrams to more complex flowcharts.

It can be incredibly useful in generating flowcharts, case timelines and decision trees. All of which are important in client interaction, internal meetings and personal use.
