GraphicsJS

Supports drawing arcs and custom shapes using mathematical functions, unlike libraries limited to standard Bézier curves, as highlighted in the README's line drawing features.

Provides multiline text, measurement, wrapping, and alignment—features not natively available in SVG/VML, making it stand out for text-heavy graphics.

Enhances drawing robustness and manageability through a virtual DOM system, reducing errors and simplifying updates in interactive applications.

Allows z-index control without redrawing the entire scene, enabling efficient visibility management for complex graphics like those in the galaxy demo.
