About this artifact — it is its own documentation
This is a single self-contained HTML file — no build step, no framework, no CDN, no server round-trips — published to Artifact Use by a coding agent in one message. What it demonstrates:
- Local-first: parsing, stats, charts, and exports all run in your browser. Data never leaves the tab.
- localStorage: your dataset and chart choices survive a reload — try it.
- URL state: "Copy share link" packs small datasets into the URL hash, so a link is the document.
- File APIs: drag-and-drop or open a local .csv/.json.
- Hand-rolled SVG charts with hover tooltips — view source, it's readable.
