Animatix is a declarative animation language and Rust rendering engine for building explanatory math, diagram, and vector animations. It ships a CLI renderer, an egui-based desktop GUI, a Tree-sitter grammar, and an LSP server.

Primitives: Text, Typst, Code, Svg, Image, Audio, Rect, Ellipse, Line, Arrow, Polygon, Path, Equation/Fragment
Plotting: Graph, PlotCurve (cartesian/polar/parametric/implicit), BarChart, VectorField, Heatmap, ContourSet, NumberPlane
Containers: Row, Col, Grid, Stack, Group, Filter, Mask
Animation: Keyframes, morphing, 20+ built-in actions (fade-in, draw-in, move, shift, rotate, scale, swap, reorder, shake, pulse, bounce, …), easing curves, sequence/stagger composition
Language: Reactive always blocks, compile-time for, pub component with slots, module imports, gradual type system, colorschemes
Multi-scene: Scene declarations, transitions (fade/wipe/cut), cross-file composition, auto-routed CLI export
Tooling: CLI renderer (image; video/GIF/WebM behind the video feature), GUI shell, Tree-sitter grammar, LSP server

A curated set of 37 runnable entry demos in examples/ covering shapes, layout, timing, morphing, reactive expressions, plotting, effects, components, modules, multi-scene, and more. See examples/README.md.
