The Basis Design System documents visual, experience, and technical standards for Basis application development: design tokens, components (cards, accordions, tabs, form controls), and content design guidance in one reference.
It's strongest in its data-visualization section specifically, documenting chart patterns built on Recharts, a level of charting detail most design systems skip entirely.
Designers or developers looking for concrete data-visualization component patterns to reference, not merely the usual buttons-and-forms coverage.
Contribution is open to internal team members rather than the public, so treat it as a browsing reference rather than an open-source kit to pull from.
A token-driven design system with clear documentation covering color, layout, motion, spacing, and theming.
