GraphTea is an open source software, crafted for high quality standards and released under GPL license. You can find more details about the source code and issue tracket on Github.

It is a perfect tool for Students, Teachers, Researchers, Game Developers and much more

The best framework for:

Drawing your graphs,

Simply using mouse, draw any kind of directed/undirected graphs and make them look special using the property editor.

Graph generators, (located under Generate Graph menu) will create these graph categories for you, based on the parameters that you provide:

• Banana graph
• Path
• Circle
• Pm*Pn
• Cm * Cn
• Star graph
• wheel graph
• K(n/d)
• Generalized Peterson
• Helm Graph
• 2partite complete graph
• Tripartite complete graph
• Complete graph
• Regular graph
• Random graph
• Random tree
• ...

Graph operations, (located under Operations menu) help you apply these graph operations on your graphs:

• Complement graph
• Power graph
• Line graph
• Paraline graph
• Total Graph
• Vertex Semitotal Graph
• Edge Semitotal Graph
• Barycentric subdivision graph
• Cartesian Product
• Union
• Disjunction
• Symmetric Difference
• Composition
• Sum
• Corona Product

For definitions and more details see this.
 

Getting information about your graphs,
Reports, (located under Reports menu), provide you with information about your graph. You can test your conjectures about different graphs. They include:

General

• Max Independent Set
• Number Of Triangles
• number of quadrangle
• Number of Stars
• Vertices Degrees List
• Is Eulerian
• Edge Degree
• Is Bipartite
• Max and Min Degree
• Number of Vertices
• Maximal Cliques
• Random Matching
• Graph Girth Size
• Maximum Cut
• Edges Degrees List
• Number of Edges
• Connected Components
• Number of Paths of Length 2
• Number of Vertices with Deg k
• Total Number of Stars

Minimum Spanning Tree

• Prim

Hamilton

• Hamiltonian Path
• Hamiltonian Cycle

Subtree Counting

• Number of Subtrees

Connectivity

• Min Cut
• Max Flow

Coloring

• All Vertex Colorings
• Chromatic Number

Matching

• Maximum Matching

Spectral

• Gomory-Hu Tree
• Spectrum of Adjacency
• Spectrum of Laplacian

Currently we are developing more reports on Topological Indices.

Running algorithms,
(located under Algorithms menu), step by step on your graph and see how they work. this is very usefull for teaching graph algorithms. you can pause, and it shows the current state of algorithm by coloring edges and vertices. This is the best tool to learn and teach graph algorithms, currently involving:

• DFS
• BFS
• Dijkstra
• Kruskal
• Prim
• Maximum flow
• Minimum cut
• Inclusion-exclusion coloring
• Acyclic checker
• Approximated vertex cover
• Biconnected components

Visualizing your graphs,
, you made a social network from your database and want to represent it in a meaningfull way? use the visualizations (located under Algorithms menu).

Present your graphs,
in your papers, websites or reports. GraphTea has a wide range of options to draw graphs, having different colors for edges and vertices. different borders and fonts and sizes and ... when you finish drawing your graph, you can save to a image file or even to a Latex document to put in your report. then you can use latexcad app, to further refine your graph.

and much more
you can make new graph generators, graph reports, file types, actions, algorithms by writing extensions. extensions provide a gateway to add new functionalities as simple as putting a file to extensions directory. you can write them using Java and Matlab. moreover you can write new extensions using any programming language that supports redis which includes almost any wellknown programming language. for more samples take a look at extensions directory
