Graphy is an educational web app for visualising graph theory, written in Node (with the express and sqlite3 modules).
Graphy has the functionality to:
- Create weighted and unweighted graphs.
- Save graphs to a server-side database (accessible by permalink), or export them as PNG images.
- Check graphs for certain properties (Connected, Hamiltonian, Eulerian, Semi-Eulerian, etc).
- Run algorithms on weighted graphs (Prim's Algorithm, Kruskal's Algorithm, Route Inspection).
