Mathlib explorer is an interactive visualization tool designed for Lean's mathlib library. It visualizes the import relations within mathlib, with carefully thought-out layout and interactions. It is a great visual representation of how math concepts are connected to each other, which can be informative even if you cannot read Lean code.

The import graph is mapped onto the plane, s.t. if B imports A, B will always be on the right of A. This makes it easy to see how modern math theories are constructed from axioms and definitions.

Supported interactions:

• Scroll to zoom in/out
• Drag to move
• Click on a node to highlight
  • its direct neighbors
  • its transitive dependents
  • its transitive dependencies
• Click on a topic label to highlight
  • all nodes in the same topic
  • references to the topic
  • direct dependencies of the topic

Clone this repo:

git clone https://github.com/Crispher/MathlibExplorer

Go to the binary folder of your platform:

cd MathlibExplorer/release/bin_{YOUR_PLATFORM}

Run the executable:

./MathlibExplorer

Limited testing has been done so far, which is mainly on MacOS (M1).

The underlying mathlib data is a bit outdated. I might update it or publish the scripts to generate the data in the future.
