Graphana 2.0

Graphana can be used to analyze the combinatorial structure of graphs. Given one or more input graph(s), Graphana computes or estimates the values and distributions of different graph parameters.

Example parameters include:

Maximum degree
Diameter
Vertex Cover size
Degeneracy
Treewidth
h-index
...

Other things, that can be done with Graphana:

Graph instance creation (e.g. with random generators)
Graph visualization
Algorithm visualization (step-by-step)
Algorithm time measurement
...

The current version of Graphana is 2.0.

Improvements:

Graphical user interface
Added algorithms
Improved algorithm efficiency
Bug fixes

Program download

Executable .jar file – the full Graphana program for analyzing graphs via basic commands
Source files – for developers

First steps

When using a shell, Graphana can be executed by typing the following command:

java -jar graphana.jar

After initialization, the main window appears. Commands can be typed in and executed by pressing Enter or the "Execute" button.

>loadDIMACS("sample.dim")
>vertexCount
6700
>edgeCount
21274
>QUIT

To get a quick help, the keyword HELP can be typed in.

See the manual for detailed usage information.
