The original react-financial/react-financial-charts repository suffered from outdated React dependencies, broken build scripts, unhandled edge cases in interactive scales, and a lack of support for modern React 18/19 concurrent features. This package resolves those legacy bottlenecks by providing a maintained, fully upgraded NPM release.
