Drug-interaction network

Native pharmacology / clinical-pharmacy network diagrams. Declare drugs (with optional therapeutic class) and pairwise interactions with effect, severity, and mechanism. Edges are colour-coded by severity (minor → moderate → major → contraindicated) and stack cleanly when one drug pair has multiple interactions. Ideal for polypharmacy reviews and pharmacology teaching.
