GoodData.UI SDK is a TypeScript/React library suite that lets developers build custom analytical apps on top of the GoodData platform (cloud or on‑premise). It provides low‑level API clients, data models, and ready‑made visual components (charts, pivot tables, geo maps, dashboards, filters, theming, etc.) for embedding analytics in web applications, targeting front‑end engineers and data‑product teams who need to create rich, data‑driven UI experiences.
