The visualization can be seen here. The static files used for the visualization can be seen on the gh-pages branch.

This test data was generated with Python 2.7.10. Use virtualenv as follows:

virtualenv pythonenv
source pythonenv/bin/activate

Then, install required packages (SQLAlchemy for the database and igraph for random graph generation):

pip install -r requirements.txt

Then, run the data generation script:

python generate_data.py

This will create users.db, a SQLite database containing users and their connections, and graph.json, a json blob with nodes and links ready to be visualized in d3.
