Grasshopper provides a node-based interface for defining geometry, data flows, and relationships.

Nodes represent functions or operations; wires represent data connections between them.

Widely used in architecture, product design, engineering, and digital fabrication.

Supports complex parametric and algorithmic design with live updates.
