“Spatial thinking is the foundation of abstract thought” - B Tversky
Cope and Drag (or CnD) is a constraint-based language
designed to help users quickly build, modify, and explore
diagrams based on Alloy and Forge instances.
The language is based on a small number of orthogonal primitives, and is grounded in the cognitive science literature on effective diagramming.
CnD is available as an npm package. You can install and launch CnD with:
npm install -g cope-and-drag
