What it is and what it does
Schemdraw is a Python library for drawing electrical circuit schematics programmatically. It provides a fluent API to place and connect standard electrical components—resistors, capacitors, transistors, opamps, and many others—and render them as high-quality SVG diagrams. Beyond circuits, it also supports timing diagrams, state machines, and flowcharts, making it useful for technical documentation, educational materials, and circuit design workflows.
The package has no external runtime dependencies, making installation lightweight. It supports Python 3.9 and later and has been actively maintained since its initial release in 2014, with a recent update 77 days ago. The library is designed for engineers, educators, and researchers who need to generate schematics programmatically rather than through GUI tools.
Use it for
- Generate circuit schematics for technical documentation and educational textbooks.
- Create timing diagrams to visualize signal behavior in digital circuits.
- Draw state machine diagrams for control system design and verification.
- Produce flowcharts for algorithm and process documentation.
- Automate schematic generation in circuit design workflows or batch processing.
