I think the best way to learn is really by way of videos, rather than books & reading. So I attach our introductory GraphJS and Phở Networks screencasts below.
GraphJS on WordPress
Writing Apps on Pho Networks
Installing GraphJS-Server on Heroku
Hope these will help you prototype your next apps more quickly as we go along.
Don’t forget, Phở is not only a platform to prototype your ideas quickly in a low-code fashion, but it also helps you build applications that are ready to scale-out infinitely.
