Each theme ships as its own package. Pass it to `createGraphyKit({ theme })`, or to `GraphProvider` as its `theme` prop. A spec names no theme, so the same spec draws in any of them, and a spec's own `styles()`, scales and `config()` sit above the theme. The provider reads the theme once, when it mounts. Pick one below to install it and see it on more graphs. A 1920s design-school poster: flat primaries, heavy black axes and a form for each group. An architect's drawing: a blue sheet, a drafting grid and hatched shapes outlined in white. A gardener's sketchbook: sepia outlines, watercolour washes and leaves on grained paper. A classroom board: shapes outlined and shaded in chalk, and handwriting throughout. A printed comic panel: four-color dots, black outlines and a hard shadow under every shape. A newspaper's business pages: salmon paper, solid rules and flat color. Two themes from Gamma's own look: a starred night sky, and a mushroom forest. One cool gray, groups told apart by lightness alone. Light and dark. A moonlit churchyard: headstones, candles, a rose window and a ghost on the line. Blunt blocks of loud color, outlined in black over a solid black shadow. A cathode-ray tube: a dark screen, glowing green shapes and a terminal face. A dark starred card in a holographic foil border, every shape one clean flat color. Ethan Schoonover's Solarized palette, a quiet grid and thin strokes. Light and dark. The graphs of a spreadsheet or slide deck: white ground, light gray rules, familiar colors. An office typescript: manila paper, a grid of hyphens and every shape typed on it. Washes of paint, colored-pen lines and handwritten labels on white paper. This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
