The diagrams doctors, engineers, and lawyers actually use.
All 45 diagram types, grouped by cluster — each follows a published standard, shows the version it shipped, and renders every example form we test.
Relationships
5Family diagram with emotional, medical, and generational notation.
Radial diagram of a client's connections to external systems.
Clinical genetic-counselling pedigree with affected/carrier states.
Rectangular cladogram from a Newick/NHX tree string.
Force-directed social network graph with edge types and weights.
Electrical & Industrial
11Digital signal timing diagram with clocks, buses, and annotations.
IEEE 91 logic-gate diagram from a gate-list DSL.
Positional circuit schematic with resistors, sources, transistors.
Transfer-function block diagram with summing junctions and feedback.
IEC 61131-3 ladder-logic program with rungs, contacts, coils.
IEC 61131-3 §6.4 function blocks wired through named ports.
IEC 61131-3 §6.5 step + transition state machine for cyclic PLC sequences.
Electrical power distribution single-line (one-line) diagram.
ISA-5.1 process equipment, valves, and instrument bubbles.
Fritzing-style breadboard view — physical wiring of Arduino / ESP32 / Pi prototypes.
AWS A2.4 / ISO 2553 welding callouts — the reference-line skeleton with weld glyphs, dimensions, and supplementary symbols placed correct-by-construction.
Behavior Modeling
5UML 2.5 / Harel statechart with composite states and pseudo-states.
OMG BPMN 2.0 — pools and lanes, events, gateways, tasks for organizational processes.
UML 2.5.1 use case diagram — captures what a system does and for whom: actors, use cases, a subject boundary, and include/extend/generalization.
UML 2.5.1 §17 interaction diagram — shows how participants exchange messages over time (who calls whom, in what order): lifelines, activations, and all twelve combined fragments.
Discrete-time Markov chain — circles + probability arcs, with the stationary distribution and recurrent/transient/absorbing classification computed for you.
Software / UML
2OMG UML 2.5.1 class diagram — classifiers (class / abstract / interface / enum / datatype / primitive) joined by the six relationship kinds, with visibility, multiplicity, and stereotypes.
Branch-and-merge commit history on per-branch swimlanes — Mermaid gitGraph compatible.
Corporate & Legal
4Corporate ownership hierarchy with percentage rollup.
Database schema diagram (crow's-foot tabular entities + cardinality glyphs).
Corporate or team reporting-line hierarchy.
ARIS business-process notation — alternating events (red hexagons) and functions (green rounded rects) joined by AND/OR/XOR connectors, with the alternation rule validated.
Causality & Analysis
4Ishikawa cause-and-effect diagram with categorised root causes.
Set-theoretic Venn / Euler diagram with 2, 3, or 4 sets.
Decision/classification tree with splits, probabilities, leaves.
System-dynamics feedback map — signed causal links the engine reads to classify each loop as reinforcing (R) or balancing (B).
Strategy
12×2 / 3×3 / N×M matrix diagrams (Eisenhower, BCG, heatmap).
Knowledge
1Radial or markmap-style mindmap from markdown headings.
Research
1PRISMA 2020 — the mandatory four-row flow diagram for systematic reviews and meta-analyses.
Project Management
2Activity-on-node project schedule that computes ES/EF/LS/LF, slack, and the critical path.
Federal function-modelling standard — boxes are activities, arrows are positional (the ICOM rule: Input-left, Control-top, Output-right, Mechanism-bottom).
Concurrency
1Risk & Reliability
4Deductive top-down reliability analysis — decompose one undesired top event through Boolean AND/OR/voting gates to basic component failures; the engine computes the minimal cut sets and the top-event probability.
Barrier-based risk management — one hazard's top event (the knot) with threats fanning in through preventative barriers on the left and consequences fanning out through mitigative barriers on the right, the whole shaped like a bow tie.
Forward-looking risk: one initiating event branches through each safety function into outcome sequences, with computed path frequencies.
The reliability worksheet that computes its own risk — RPN = S×O×D plus AIAG-VDA Action Priority, ranked and colour-coded.
Network & Infrastructure
2IT / CCTV network topology with Cisco-convention device icons, typed links, subnets/VLANs, and topology-correct layout.
Security data-flow diagram where the engine annotates each element with its applicable STRIDE threats and flags every flow that crosses a trust boundary.
