Animated diagrams, live on this page
Scroll to each diagram below to trigger the animation. These are the same components available for embedding on your site.
Sankey (flow diagram)
Pipeline stages (process)
Evidence pyramid (hierarchy)
Charts versus diagrams: what is the difference?
Charts plot quantitative data against axes: a bar chart compares magnitudes, a line chart shows change over time, a scatter plot shows correlation. Diagrams show structure, process, and relationship: a sankey diagram shows where flow goes, a pipeline shows stage-by-stage progression, a network shows connections between entities.
Both are in the Scrollchart catalog. This page focuses on the diagram types, the ones that explain how something works or how things connect rather than how much.
Diagram categories in the catalog
The catalog organizes animated diagrams into these structural types:
- Flow diagrams: sankey (two-stage, three-stage), alluvial flow, arc flow, chord diagram, directed process flow
- Process diagrams: pipeline stages, gantt chart, event timeline, cycle loop
- Hierarchy diagrams: evidence pyramid, treemap (flat and hierarchical), sunburst, icicle
- Research and clinical: PRISMA flow, CONSORT flow, forest plot, funnel plot, ROC curve
- Network diagrams: force-directed network, parallel coordinates, parallel sets
- Comparison diagrams: radar chart, bubble chart, scatter matrix, marimekko
Why animation matters for diagrams
A static sankey diagram asks the reader to trace each flow band individually with their eye, all at once. An animated sankey that builds stage by stage lets the reader follow one flow at a time, matching the order a written explanation would use. Animation is not decoration here. It is the presentation logic.
The same principle applies to process pipelines (each stage appears in sequence, reinforcing left-to-right reading), evidence pyramids (layers build from base to apex, echoing how evidence hierarchies are explained verbally), and flow diagrams of all kinds.
Embedding an animated diagram
Every diagram in the catalog has a two-line embed snippet:
<div data-scrollchart="sankey-flow"></div>
<script src="https://scrollchart.com/embed.js" async></script>
Replace sankey-flow with the slug of any catalog diagram. The embed loads from scrollchart.com, paints when the reader scrolls to it, and includes a tabbed explainer panel. For WordPress, use the plugin's Gutenberg block or the [scrollchart id="sankey-flow"] shortcode.
Free forever
The diagram and explainer text are served from scrollchart.com so the content can be updated over time to reflect new research or to link to relevant sources within the explainer. No subscription, no ads, no tracking pixels served to your readers.
Frequently asked
Where can I find free animated diagrams for my website?
Scrollchart provides a free catalog of animated diagrams you can embed with one line of HTML. No signup, no watermark. The catalog covers flow diagrams, sankey charts, process maps, distribution plots, network diagrams, and more across 17 subject categories.
What is an animated diagram?
An animated diagram is a data visualization that renders its shapes, paths, and labels progressively rather than appearing all at once. In the Scrollchart catalog, diagrams paint themselves in when the reader scrolls them into view, using IntersectionObserver and CSS transitions built on inline SVG.
How do animated diagrams differ from animated charts?
Charts plot quantitative data on axes (bar, line, scatter). Diagrams show relationships, processes, and structures (sankey flows, process pipelines, network connections, hierarchy trees). The Scrollchart catalog includes both: animated charts for data and animated diagrams for process and relationship visualization.
Will an animated diagram hurt my Core Web Vitals?
No. Every diagram in the catalog lazy-loads via IntersectionObserver, so it does not affect first paint or Largest Contentful Paint. The container height is reserved in advance to prevent layout shift. Bundle size is approximately 25 KB gzipped per diagram.
Can I embed animated diagrams in a science or research article?
Yes. The catalog includes diagrams designed for health-science, statistics, and research contexts: PRISMA flow diagrams, evidence pyramids, forest plots, CONSORT diagrams, and more. All are free to embed under the Scrollchart terms.
Are animated diagrams available in languages other than English?
Yes. Scrollchart's animated diagrams render labels, axis titles, captions, and source lines in every major language — English, French, Spanish, German, Mandarin, Hindi, Arabic, Japanese, Portuguese, and more. The scroll-driven animation logic is language-agnostic; only the rendered text differs.
