Author data-visualization and math-visualization scenes in ecmanim — the D3-parity foundation (scales, shape generators, hierarchy layouts, force simulation, sankey/chord, contours/hexbin/topojson, dataJoin for enter/update/exit), chart mobjects (PieChart…
Author, render, and iterate on ecmanim animations (a TypeScript port of manim that renders the same Scene code in Node and the browser). This skill should be used when the user wants to create or edit a Manim-style programmatic animation with ecmanim, render…
Interchange and fidelity workflows for ecmanim — playing back real animated Lottie/Bodymovin files (`loadLottie` → `LottieMobject`, scrub-safe keyframes/masks/mattes/precomps), exporting/importing static Lottie shape JSON (`loadLottieShapes`), exporting…
Author physics visualizations in ecmanim — analytic electromagnetic fields (point charges, current loops), traveling/standing waves, paraxial thin-lens optics, rigid-body simulation (pendulum, gravity/floor drops, pluggable planck.js/@dimforge/rapier2d…
Build slide-style/presentation ecmanim scenes — automatic shared-element transforms between two mobject states (TransformMatchingAuto, identity-keyed not position-keyed, plus Scene.autoAnimateToNextSection() and the GSAP-style FLIP helper), presenter/slide…
Covers the `ecmanim` command-line tool — the render/plan/cfg/init/plugins/checkhealth subcommands, render flags (-q quality presets, -f output formats, -o output path, -t transparent, -a write_all, -n from_upto, --save_sections), the manim.config file, the…
Sequence and time ecmanim animations with the GSAP-style Timeline position grammar, drive properties with pure expression functions (wiggle/remap/ramp/compose), distribute per-element delays with stagger helpers (cycle/staggerRange/staggerGrid +…
Practical field guide for authoring ecmanim scenes — layout math that prevents clipped/off-center output, a verification discipline that catches problems before they reach the user, working layout helpers (frame geometry, measured text width, Axes centering),…
