diagram-animation

diagram-animation is a skill for Claude Code from iart-ai/explainer-video-skills. It costs 91 tokens per session (2,258 once invoked), scanned A, original, MIT.

A guide for animating diagrams and data visualisations by revealing nodes, connections, charts, and labels over time.

In plain words
What is it for?
Building step-by-step flowcharts, architecture and sequence diagrams, animated bar or line charts, process explainers, and moving data connections.
Why use it?
It makes complex structures and changing data easier to follow than showing everything at once.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

diagram-animation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Diagram & Data Animation

Make structure and data legible by revealing it over time — one idea per beat. Build progressive node/edge reveals, flowing connectors, and animated charts (bars grow, lines draw, numbers count up) for web or video.

When to use

  • Architecture, flow, or sequence diagrams that build step by step.
  • Animated charts: bars grow, lines draw on, numbers count up.
  • "How it works" walkthroughs and process explainers.
  • Showing data or signal flowing along connectors.

Core principle: progressive disclosure

Never show everything at once. Reveal in this order: nodes → edges → labels. Highlight the active element and dim the rest (focus + context). Pace to comprehension, not flash — hold each step 0.5–1.5s so it lands. Keep a consistent visual grammar: color means meaning, and that mapping never changes mid-piece.

Quick reference

Goal Mechanism Easing
Node appear scale 0.8→1 + opacity, transform-origin:center back.out(1.5) / easeOut
Edge connect stroke-dashoffset len→0 easeInOut, 0.4–0.7s
Flowing data animate stroke-dashoffset looping + traveling dot linear, infinite
Bar grow scaleY 0→1, transform-origin:bottom easeOut, stagger 0.06s

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
