d3/d3-dispatch

d3-dispatch is a low-level interaction mechanism for D3.js that allows developers to register named callbacks and trigger them with arbitrary arguments. It serves as the foundation for event handling in various D3 components, similar to Node's EventEmitter but with explicitly named listeners for easy management. This library is designed for developers working with D3.js who need fine-grained control over event dispatching in their data visualizations or interactive components.
