Mosaic is an extensible TypeScript framework that links interactive data views (plots, tables, widgets) to a backing DuckDB database for scalable processing. Components publish declarative SQL queries that a coordinator manages, optimizes, and cross-filters, enabling interactive exploration of millions to billions of records in web apps or Jupyter notebooks.

Use cases

• visualize and explore datasets with millions or billions of records interactively
• build data-driven web dashboards backed by DuckDB
• cross-filter linked charts and tables in the browser
• analyze large datasets interactively in Jupyter notebooks
• run client-side analytics with DuckDB-WASM in the browser
• create custom extensible data-driven view components

When to choose

• you need interactive visualization of very large datasets beyond what in-memory JS tools handle
• you want linked/cross-filtered views powered by a real SQL engine
• you want DuckDB either server-side or in-browser via WebAssembly
• you want a declarative visualization grammar (vgplot) with extensible architecture

When to avoid

• you need simple static charts of small datasets where a lighter library suffices
• your stack requires a database other than DuckDB
• you need server-side rendered images rather than interactive web views
