  If you have attempted to integrate D3.js into a modern React application, you have likely encountered the "black box" problem. You initialize a   ref , pass it to a   useEffect   hook, and write imperative D3 code to mutate the DOM manually. It works, until it doesn't. React’s Strict Mode causes double-invocations that duplicate your axes. State updates desync because D3 is manipulating DOM nodes that React believes it controls. You end up writing complex cleanup logic just to prevent memory leaks. There is an architectural friction here:  D3 wants to be the UI library, but React demands to be the UI library. Airbnb’s Visx library resolves this conflict not by replacing D3, but by unbundling it. It allows us to use D3 for the mathematics (scales, paths, generators) while letting React handle the rendering. The Root Cause: Imperative vs. Declarative Conflict To understand why Visx is necessary, we must analyze why standard D3 implementation fails in React. Reac...
