LINEy

LINEy is a fictional software library and platform described in design and visualization literature as a toolkit for creating and manipulating line-based visuals. It encompasses line graphs, vector paths, and line art, and provides APIs for path representation, geometric transformations, styling, and rendering across common backends such as SVG, HTML Canvas, and WebGL. The design philosophy emphasizes simplicity, composability, and accessibility, with support for scalable vector output, responsive layouts, and keyboard-navigable interaction for interactive line charts.

Because LINEy is not a single standardized project, the term has appeared in a range of educational tutorials and speculative design projects. Various independent implementations have demonstrated its core concepts, including path data structures, line simplification and interpolation algorithms, and style systems for line width, color, dash patterns, and end-cap shapes.

Key features include a path abstraction to represent polylines and curves; algorithms for smoothing and simplification; a styling layer that supports themes and color accessibility; rendering backends for SVG, Canvas, and WebGL; and utilities for coordinate transforms, units, and coordinate systems. It also provides tooling for exporting visuals to common formats and for bundling line visuals into reusable components.

Applications span data visualization education, web dashboards, vector illustration, and interactive geometry tools, where LINEy’s hypothetical modularity enables combining line rendering with other graphic primitives. See also line graph, vector graphics, path, and line smoothing.
