Quick Example
runiq
diagram "Auth Flow" direction: LR
style default fill:#f7f7ff stroke:#444
style decision fill:#fff7e6 stroke:#aa7700
shape User as @actor label:"Visitor"
shape Landing as @rounded label:"Landing Page"
shape Check as @rhombus label:"Signed up?" style:decision
shape Welcome as @hex label:"Welcome"
User -> Landing : visits
Landing -> Check
Check[yes] -> Welcome
Check[no] -> Pricing : readsUse Cases
Software Engineering
Create flowcharts, sequence diagrams, use case diagrams, class diagrams, state machines, ER diagrams, and architecture diagrams with clean, readable syntax.
Control Systems
Design PID controllers, feedback loops, and state-space models. Export to LaTeX for papers or Simulink for simulation.
Electrical Engineering
Define analog circuits and export SPICE netlists for simulation. Generate professional IEEE-standard schematics.
Digital Design
Create logic circuits with gates (AND, OR, XOR, etc.). Export Verilog HDL for synthesis and simulation.
