UI component library reference for Composable Svelte. Use when implementing designs, choosing components, styling layouts, or working with shadcn-svelte components. Covers component props, variants, accessibility patterns, visual composition, and when to use which component. For specialized components see composable-svelte-graphics (3D), composable-svelte-code (editors/media), composable-svelte-charts (visualization), composable-svelte-maps (geospatial).

Data visualization and chart components for Composable Svelte. Use when creating charts, graphs, or data visualizations. Covers chart types (scatter, line, bar, area, histogram), data binding, state-driven updates, interactive features (zoom, brush, tooltips), and responsive design from @composable-svelte/charts package built with Observable Plot and D3.

Streaming chat and collaborative features for Composable Svelte. Use when implementing LLM chat interfaces, real-time messaging, or collaborative features. Covers StreamingChat (transport-agnostic), presence tracking, typing indicators, and WebSocket integration from @composable-svelte/chat package.
