NathanFlurry/VisualProgrammingLanguage

This system is a legacy educational codebase centered around the WWDC18 playgroundbook, which provided visual programming tutorials and machine learning models via the VPLEditor framework. Although the core content and associated resources were completely removed in 2018, the repository persists with recent activity focused on fixing source code within that deprecated playgroundbook structure. Consequently, the system currently serves as a maintained archive of obsolete educational material rather than an active development platform.

10 changes.

This period focused on the creation and refinement of the WWDC18 playgroundbook, including the initial release of the VPLEditor framework and the addition of machine learning models and visual programming tutorials. Significant effort was spent updating chapter content, such as introducing custom visual nodes and revising the introduction and conclusion sections. The period concluded with the complete removal of the WWDC 2018 playgroundbook content, deleting the associated chapters and resources.
