GraphvizAnim is a tool to create simple animated graph visualizations; it is

just a proof of concept, aimed mainly at teaching purposes. It is based on

[Graphviz](http://www.graphviz.org/) for the graph rendering part and on

[ImageMagick](http://www.imagemagick.org/) for the animated gif generation. You can [run the heap sort animation](https://mybinder.org/v2/gh/mapio/GraphvizAnim/master?filepath=examples/heapsort.ipynb) on-line using [binder](http://mybinder.org/).









A *graph animation* is just a sequence of *steps*, a step is in turn one or

more *actions* such as: *add*, *hilight*, *label*, *unlabel* or *remove* a

*node*, and  *add*, *hilight*, or *remove* an *edge*. Animations can be built

by invoking suitable methods of a `gvanim.Animation` object (in a Python

program), or by parsing a simple text file (that, in turn, can be generated by

a program in any language).

The [examples](examples) folder contains few instances of such approaches.

After installing the package with `python setup.py install`, or using

	pip install GraphvizAnim

you can generate an animated depth first visit (in a 3-regular random graph of

6 nodes) by running

	python examples/dfv.py

or you can generate the simple animation described in

[simple.txt](examples/simple.txt) as

	python -m gvanim examples/simple.txt simple

You can generate an [Erdős–Rényi](https://en.wikipedia.org/wiki/Erd%C5%91s%E2%80%93R%C3%A9nyi_model) graph (with 10 nodes and edge probability

1/10) by running

	cd examples

	gcc -o er er.c

	./er | python -m gvanim er

Finally, you can obain an interactive visualization of the *heap sort*

algorithm using [Jupyter](http://jupyter.org/) by running

	cd examples

	jupyter notebook heapsort.ipynb

and running all the cells in order; or you can give a try to

[binder](http://mybinder.org) and watch the above animation

[actually running](https://mybinder.org/v2/gh/mapio/GraphvizAnim/master?filepath=examples/heapsort.ipynb) on-line.
