Open Hypergraphs

A library for representing the two-dimensional syntax of string diagrams. Use it if you think of your data in terms of "boxes and wires" like this:

          ┌───┐
      ────│ f │────┐    ┌───┐
          └───┘    └────│   │
                        │ h │────
          ┌───┐    ┌────│   │
      ────│ g │────┘    └───┘
          └───┘

A concrete example: neural networks, where wires carry tensors (e.g. a 3×4 matrix) and boxes are tensor operations (e.g. matmul)
