SchemDraw Web Runner

A simple web-based editor for schemdraw, a Python library for producing high-quality electrical circuit schematic diagrams.

Features

• Live Python Editor: Write schemdraw code directly in your browser.
• Instant Rendering: Generate SVG diagrams without installing Python locally.
• Export to PDF: Save your diagrams as high-quality PDF files.
• Zero Backend: Powered by Pyodide, running Python entirely in the browser via WebAssembly.

How to use

1. Wait for the environment to load (it will install schemdraw in the background).
2. Enter your Python code in the editor. Use the d object which is pre-initialized as a schemdraw.Drawing() instance.
3. Click Render Diagram.
4. Click Export PDF to print or save the diagram as a PDF.

Example Code

d += elm.Resistor().label('100Ω')
d += elm.Capacitor().down().label('10μF')
d += elm.Line().left()
d += elm.SourceV().up().label('12V')
