Mapping the architecture of story—arcs, tensions, and turns—in the shape of a single drawn line.
Vonnegut sketched curves on a chalkboard—Man in Hole, Boy Meets Girl, Cinderella—and argued that every plot has a graphable silhouette. plotgrapher continues the chalk line.
A plot is reduced to two numbers per scene—a position in time and a magnitude of tension. The pairs are smoothed into a continuous curve. The curve is read.
Break the narrative into discrete beats. Each beat receives a coordinate: x as fractional time within the work, y as a normalized tension score from 0 to 1.
Label each point with its dramatic function—exposition, inciting incident, midpoint reversal—so that the curve carries the literary nomenclature alongside the geometry.
Interpolate a smooth bezier through the points. The result is a story rendered as a single continuous gesture, drawn on the plane of time and tension.
Compare curves. A symmetric arc reveals classical structure; an end-loaded peak signals modernist suspension; a flat line with a single spike is the shape of a thriller.
A small reading-room of voices on shape, structure, and the geometry of fiction.
I have tried to persuade you that the simple shapes of stories are graphable, and even beautiful.
— Kurt Vonnegut, Palm Sunday, 1981
Every novel is, in a sense, a plotted line that has been compressed into language; the critic's task is to find, again, the line.
— James Wood, How Fiction Works, 2008
The arc is not the story. The arc is what the story leaves behind once the words have been forgotten.
— Ursula K. Le Guin, Steering the Craft, 1998
Two narratives plotted on the same plane reveal their differences not in summary but in silhouette.
