AnimateGraphViz 1.1.1

GraphvizAnim

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 for the graph rendering part and on
ImageMagick for the animated gif generation. You can run the heap sort animation on-line using binder.

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 animategv.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 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 as
python -m animategv examples/simple.txt simple

You can generate an Erdős–Rényi graph (with 10 nodes and edge probability
1/10) by running
cd examples
gcc -o er er.c
./er | python -m animategv er

Finally, you can obain an interactive visualization of the heap sort
algorithm using Jupyter by running
cd examples
jupyter notebook heapsort.ipynb

and running all the cells in order; or you can give a try to
binder and watch the above animation
actually running on-line.
