Raphael

Uses SVG for modern browsers and VML for Internet Explorer 6-8, ensuring compatibility with older web environments, as highlighted in the README's focus on broad support.

Provides simple functions like Raphael.rect() to create shapes, making vector graphics accessible without deep SVG knowledge, per the quickstart and examples.

Includes methods to animate attributes over time, such as .animate(), enabling motion effects without external libraries, as noted in the key features.

Allows attaching DOM-like events to vector objects for interactivity, supporting mouse and touch events, which is essential for charts and diagrams.
