Graph
The Letters · Mark Gowing · 2017

A strictly angular geometric sans built entirely on perpendicular and 45-degree angles, with no curves, designed by Mark Gowing for his own poster design monograph.
About
Originally sketched on graph paper in 1991 and revised for publication in 2017, Graph is constructed from a metric grid using only perpendicular and 45-degree angles — every stroke is straight, every curve absent. Stroke contrast emerges not from calligraphic tradition but from the compression of angled strokes bisecting the grid. The eight-style family covers three weights with italics and a dedicated display cut, applying more classical sans-serif proportions than the original sketch to keep it legible at text sizes.
Classification
Graph is built entirely from perpendicular and 45-degree angles on a metric grid, with no curves and stroke contrast derived solely from angled strokes — a rigidly geometric, angular sans-serif with display and text cuts.
