• (optional) use the data returned via the graph state object (e.g. selected node or edge, ...)

Run Example App

• create the environment
  • pip install virtualenv (if you don't already have virtualenv installed)
  • virtualenv venv to create your new environment (called 'venv' here)
  • source venv/bin/activate to enter the virtual environment (unix)
  • venv/bin/activate to enter the virtual environment (windows)

pip install -r requirements.txt to install the requirements in the current environment
