Hollow Diagrams
Diagrams you can draw or write as code.
Create architecture diagrams and flow charts from boxes, decisions, data stores and frames, with shapes that snap to the grid and connectors that stay attached as you drag.
- Diagrams as code
- Snap-to-grid shapes
- SVG, PNG & PDF export
What it does
What you can do in Diagrams
Connectors that stay tidy
Snap-to-grid shapes and straight, orthogonal or curved connectors keep relationships clear as the canvas grows.
Edit as code
Open any diagram as YAML or JSON, change the structure in text, then apply it back to the canvas.
Export where you need it
Export to SVG, PNG, PDF, YAML or JSON when a diagram has to leave the workspace.
