Built in under 500 lines, it tracks forward, inverse, and upstream dependency relationships between datums. Key features include topologically sorted change propagation to avoid redundant re-evaluations, hierarchical subgraphs with explicit input/output boundaries for information hiding, and correct-by-construction graph state. The post also compares Graphene to Antimony, noting improvements like eliminating the node/subgraph distinction and preventing duplicate identifiers. ## Full article daily.dev links to this article rather than hosting it.
