Morphing chart animations in a browser

Morphing animations between arbitrary chart states in a web client application are provided. A morphing animation engine interpolates changes between a first output state (before geometry) and a second output state (after geometry), aligning the before and after geometries by semantic identifiers encoded in the geometry. The morphing animation engine further performs simple geometric transitions of geometric primitives for producing an unlimited number of intermediate states (key frames) between any two arbitrary chart states without requiring per frame layouts. According to an aspect, processing times for producing intermediate frames are minimized, allowing for animations to have consistent rendering and achieving a high frame rate (60 FPS).
