Tessera
Paste any feed — CSV, TSV, JSON or JSON-lines — and Tessera instantly builds a dashboard: it sniffs the delimiter, infers every column type, then lays out stat tiles, seven interactive canvas charts (bars, ranked bars, line, area, donut, histogram, scatter) with touch tooltips, plus a live data preview. Each chart has its own group-by / measure / aggregate controls; export the board as a 1200×630 PNG or copy a Markdown digest. Zero dependencies, no build step, fully offline, and every colour and sample feed is a plain const in js/config.js — made to be remixed.
