Reading order
Load concentration is a grid question (heatmap, contour, stripes); trend and outlier views answer the follow-up "since when".
Engines in this goal
echarts— report-grade charts and dashboardsinfographic— template-driven boards, sequences and comparisonsvega/vega-lite— statistical views where the data needs transforms
Details, limits and anti-patterns: ../engines/echarts.md · ../engines/infographic.md · ../engines/vega.md.
Palette
Every figure takes its colours from a theme. Pick one in
../styles/palette.md — the token contract, the theme index and the
per-engine blocks all start there.
Most figures in this set want Default. Depart from it for the medium, not the topic: Print when it may be photocopied, Contrast for low vision or large-print handouts, Vivid when it will be projected, Accessible when colour must not be the only cue, Editorial for long-form reading, Slate for technical reference, Pastel when the figure sits inside gentle prose, Nord for a cool Nordic register. Every theme is designed for a light ground — the set has no dark page.
Don't
- An auto-scaled heatmap hiding the floor → pin the domain
- Reading contour lines as probabilities → they are density levels
