Mosaic: Scalable interactive data visualization for the browser

We’ve gotten used to the idea that analyzing big data means shipping it off to a cloud warehouse. But your laptop is faster than you think. Mosaic is an open architecture that runs interactive visualizations over billions of records entirely on your machine, backed by DuckDB in WebAssembly or a local database—no cloud and your data never leaves your machine. I’ll show live demos of fluidly exploring massive datasets, explain how Mosaic coordinates linked charts, tables, and filters through declarative queries, and share what we learned enabling client-side analysis at the speed of human thought.
