Tessera
Tessera turns any pasted feed into a live dashboard. Drop in CSV, TSV or JSON and it autodetects the shape (delimiter sniffing, JSON array/columnar/lines), infers column types, then assembles stat tiles plus bar, line, donut, histogram and scatter tiles you can build and remove on the fly. Feeds persist locally, export as CSV, and share via a link that carries the data. Fully config-driven and dependency-free — no build step — so it is easy to remix and retheme.
