Graphviz Tutorial

Graphviz Tutorial

Learn the DOT language step by step and start drawing graphs by hand.

Graphviz turns a short text description — the DOT language — into a rendered graph: flowcharts, dependency trees, state machines, architecture diagrams. Once you know a handful of DOT keywords, hand-writing a diagram is often faster than dragging shapes around a canvas.

This tutorial covers nodes, edges, and their attributes (shape, color, labels) with a small exercise at each step. You write the DOT snippet and we check the rendered graph against the expected result.

What you'll practice (7 steps)

• Graph node
• Two nodes
• Node Attributes
• Edges
• Edge Attributes
• Nodes and Edges wrap up
• Subgraphs & clusters
