Vivus is a lightweight JavaScript library designed to animate the drawing of vector graphics within web browsers. It functions as a specialized motion framework that renders and animates complex illustrations by progressively revealing SVG path strokes.
The library enables the creation of fluid, programmatic drawing effects for icons and decorative elements. By manipulating path lengths and synchronizing updates with the browser refresh rate, it provides a controlled method for applying motion to static vector assets.
The engine supports custom timing and sequencing through declarative easing functions and lifecycle hooks. These capabilities allow for the orchestration of multi-step visual transitions and the dynamic modification of element attributes during the animation process.
