Core Concepts

How data moves through a graph.

Elements, ElementSets and Attributes

How OctoShaper moves data through a graph: ElementSets are tables, attributes are columns, and nodes read and write them by name.

Sync vs Async

What changes when a graph runs asynchronously, in editor previews, on the executor and from code.
