A framework for building higher-order graph data structures

import { GraphSpec, Dataflow } from './types.js';
/**
 * Creates a dataflow computation graph for lazy evaluation of dependent calculations.
 * Nodes represent computations and edges represent data dependencies.
 *
 * @param spec - Graph specification defining the computation nodes and their dependencies
 * @param options - Optional configuration for graph format
 * @returns A dataflow instance that can be instantiated with input data
 *
 * @example
 * ```typescript
 * const flow = dataflow({
 *   nodes: [
 *     {key: 'a'},
 *     {key: 'sum', calc: (flow) => (a, b) => a + b}
 *   ],
 *   edges: [
 *     {key: 'dep', value: {source: 'a', target: 'sum'}}
 *   ]
 * });
 * const instance = flow.instantiate({sum: 10}, {a: 5});
 * console.log(instance.calc('sum')); // 15
 * ```
