TUFTE — DATA VISUALISATION — MAXIMUM INFORMATION DENSITY

VISUAL STYLE: Data visualisation in the tradition of Edward Tufte. Maximum information density. No chartjunk. No decoration that does not carry data. The elimination of every pixel that does not communicate — and then the question of whether the remaining pixels communicate as efficiently as possible.

COLOUR PALETTE: White (#FFFFFF) or light grey (#F5F5F5) as the ground — data needs a clear surface. Black (#000000) for primary data marks and axis lines. Deep grey (#555555) for secondary information. Single accent colour — deep teal (#006E6E) or warm red (#CC2200) — used only where colour encodes information, never decoration.

DATA MARKS: Small, precise, numerous. The value of Tufte's approach is that many data points can occupy a small space without confusion — because nothing unnecessary competes for attention.

SMALL MULTIPLES: The same graphic, repeated with variation — the most powerful technique for showing change across time, condition, or category. Each small chart is identically structured. Differences are immediately visible.

TYPOGRAPHY: Minimal and precise. Labels at data points rather than legends. Axes labelled at their ends rather than their centres. The type serves the data, never the design.

RATIO: Data-ink ratio maximised. Every mark carries information. If a mark can be removed without losing data, it is removed.

No decorative illustration. No three-dimensional charts. No gridlines heavier than the data they frame. Only data, and the marks required to show it, throughout.
