Maps and data motion: travel maps, charts, counters and audio visualizers

Eight animations where the data or the place is the story. One paused timeline drives the camera, the numbers and the audio bands, so a frame renders the same on every pass, and the map credits are designed in rather than pasted on.

Gates

• Licensed tiles and credits. Vector maps from Natural Earth (public domain) need no credit. Satellite and street tiles need the provider's plan and its credit string on screen; never render from tile.openstreetmap.org.
• The person's real numbers. Charts and counters show data the person gives you, with its source; never round a number into a different claim.
• Seek-safe. Every value is a function of timeline time; randomness is seeded by frame. No Date.now(), requestAnimationFrame or unseeded Math.random().
• No credits here. These templates render locally for free. Generated footage, voice or music is the varg-ai skill: call estimate_cost and wait for the person's approval before any generation.

Pick a template

8 templates, 25 presets. Each reference file has the same sections: how the pros do it (every rule cited), presets, timing and numbers, how to build it, mistakes that look amateur, sources. Each JSON file holds the same presets as machine-readable values.

| Template | Use it for | Presets | Files | |---|---|---|---| | Audio visualizer | Turns a soundtrack into silk ribbons, a scrolling wireframe terrain or an ASCII character field. | Silk ribbons, Wire terrain, ASCII stream | audio-visualizer.md · json | | Count-up statistic | One big number counts to its value over footage or a plain background, lands with a small pulse and holds with a label. | Centre hero, Corner tag, Lower band, Split compare | count-up-stat.md · json | | Globe-to-country dive | A globe turns and zooms onto one country, which lights up and gets a label. | Night globe, Atlas paper, Flat brand | globe-country-dive.md · json | | Satellite flyover between two places | Camera lifts off over place A on satellite imagery, flies an arc and settles over place B while the route draws. | Daylight, City lights, Slate | satellite-flyover.md · json | | Self-drawing bar and line chart | Bars grow from a zero baseline or a line draws with its value riding the tip, then one datum is highlighted. | Bars, Line, Editorial | self-drawing-chart.md · json | | Vector route map | A route draws itself across a flat vector map with a traveller riding the line and stops popping in. | Clean light, Night transit, Multi-stop itinerary | vector-route-map.md · json | | Versus timeline | Two values move in opposite directions on a shared axis while a year counter ticks, ending with a gap callout. | Light paper, Dark ink, Footage overlay | versus-timeline.md · json | | Watercolor travel route | A hand-painted watercolour map where a dashed ink route draws between two places with handwritten labels. | Travel journal, Bold wash, Antique | watercolor-route-map.md · json |

Workflow

1. Match the request to a template and one or two presets from the table. Say which and why in one line, and show the person the preset names with their one-line looks before building anything.
2. Read the reference for that template, and load its JSON. Take values from the JSON; do not re-guess them.
3. Build it the way the reference's "Build it" section says, starting from the named HyperFrames blocks or varg components where it names them. Drive every value from timeline time so any frame renders the same on a re-render.
4. Fit it to the brand: swap in the person's colors and fonts only where the reference allows, then re-check contrast and safe zones with the numbers in "Timing and numbers".
5. Check a draft: render stills at the key moments (entrance, hold, exit), go through "Mistakes that look amateur", and fix before the final render.

Rules that hold for every template

1. One paused timeline drives everything: map cameras via per-frame jumpTo (never flyTo's own clock), counters via a tweened proxy, audio via precomputed per-frame arrays.
2. Camera moves use the van Wijk zoom-pan curve (rho 1.42 in MapLibre, √2 in d3), scale interpolated in log space, about one zoom level per second.
3. About 1 s per simple transition, slow-in slow-out, staged (axis/camera first, values/colour second), stagger 0.05–0.08 s (Heer & Robertson).
4. Bars start at zero, lines need not; one accent series, the rest grey; direct labels instead of legends; units in the subtitle.
5. Numbers: tabular figures, compact notation, 2–3 significant digits, signed deltas; count with easeOutExpo cubic-bezier(0.16,1,0.3,1), linear-then-ease above 999.
6. Build maps as vector (SVG/canvas from Natural Earth, public domain) so every part animates; raster only for imagery.
7. Credits are part of the design: OSM corner credit while the map leads, © Mapbox / © Maxar, the Esri string, the Google Earth watermark; EOX imagery is non-commercial unless licensed; never render from tile.openstreetmap.org.
8. Audio: FFT 4096 per frame, log bands 30 Hz–16 kHz, dB −100…−30, per-band normalisation, fast attack / 150–600 ms release, text reacts at most 4–6%.
9. Holds get only quiet ambient motion (shimmer, dash crawl, 1–2% push-in), never bouncing.

Every rule in the references cites its source by number. The full list, with links and what was taken from each, is in references/sources.md. Values marked as house defaults in a reference are our own starting points where no expert published a number.
