What kind of experience / background do I need to have in order to use Graph?
Graph is designed for several types of users.
For folks coming out of online progamming courses like Codecademy, Treehouse, General Assembly, etc, Graph offers a fantastic next-step in your development path. They can leverage what they've learned and build actual apps and websites without having to worry about the heavy lifting.
For founders with little-to-no dev experience, Graph offers the ability to hammer out ideas to see if there's a "there" there. They can get their idea 70-80% of the way down the road and then turn it over to freelance help to get a proof-of-concept out the door in days.
Graph enables developers to iterate and ship more quickly. It enables them to focus on the bigger problems at hand instead of waffling on concepts that are either more advanced than their current experience enables or easier to hand off than mess with.
