Graph Code parses and runs a script into animated graphs and other graphics. It comes with one default script which you can modify or completely replace with your own script. This is intended to be an educational application to permit the user (you) to experiment with different scripts and programming concepts. Writing a script requires a substantial amount of knowledge and resources and for that reason Graph Code does not even attempt to be comprehensive. Rather, Graph Code is intended to be an entrance point to other resources and exploration.
To operate Graph Code, touch the Source tab and enter or modify source code in the text view. Then touch the Graphics tab to render the graphics and animate it. The animation period is pre-set to 1/10th of a second.
The scripting is very general and can conceivably be used to write an application without further tools. If you are accustom to Xcode and programming for iOS devices then you may be interested in the projects at: GitHub.com/VVI one of which is the project to build this application.
