- A utility library for simplifying D3 rendering logic with unidirectional data flow.
While frameworks like React, Svelte, Vue, and Angular offer state management and DOM manipulation solutions, D3 excels in data transformation and visualization, particularly with axes, transitions, and behaviors (e.g. zoom, drag, and brush). These D3 features require direct access to the DOM, making it challenging to replicate them effectively within frameworks.
Unidirectional data flow is a pattern that can be cleanly invoked from multiple frameworks. In this paradigm, a single function is responsible for updating the DOM or rendering visuals based on a single, central state. As the state updates, the function re-renders the visualization in an idempotent manner, meaning it can run multiple times without causing side effects. Here's what the entry point function looks like for a D3-based visualization that uses unidirectional data flow:
