To set up your development environment, you need pip (included with Python>=2.7.9).
If you don't have it already, install virtualenv:
pip install virtualenv
Then, create a virtual environment in the civic-graph folder:
virtualenv civicenv
Activate the virtual environment with:
.\civicenv\Scripts\activate # (Windows)
source civicenv/bin/activate # (Mac/Linux)
Then you can install the required packages with:
pip install -r requirements.txt
Finally, you can run the application on http://localhost:5000:
python run.py
