Penrose
Penrose is a platform that enables people to create beautiful diagrams just by typing notation in plain text.
Penrose diagrams consist of three parts:
-
.domain file that defines the language specific to the domain.
-
.substance file that creates substances of mathematical content.
-
.style file that specifies the style of the visual representation.
The domain and style files are specified using attributes. The substance of the diagram is the block contents.
