Accessible viz: 1917 (2026)United States (US) Institutional & Field Benchmark
US- Primary reference framework
- Charts, diagrams, and studio craft with a widened workspace — pick forms, then open the studio to build.
- Verification standard
- Season lens: report and deck season favors defaults with strong contrast and print-safe palettes — open studio early.
- Metric & unit convention
- Accessible viz · 1917 (2026)
Viz pages teach chart and diagram craft for browsing and studio work — not a substitute for data ethics review or accessibility audits on shipped reports.
Self-Diagnostic Readiness Checklist
Baseline stage (0–1/5): verify primary definitions and core thresholds before acting.
5-Step Execution & Verification Playbook
- Paste stays on this device — JSON you paste or restore never uploads. The studio keeps work in browser memory and local storage only.
- sanitizeDoc and guards before render — sanitizeDoc bounds the doc, then guardShape, guardChart and plainText run on every load path. Unknown fields drop; bad docs reject instead of drawing raw.
- Recent boards are local — The recent list is saved on this browser. Opening or comparing a snapshot still runs sanitizeDoc first; guards are not skipped on restore.
- Coworker export never POSTs — A file or string from a teammate is read locally. Nothing is posted to Tool-Lifes or a third-party ingest endpoint.
- Compare is a second sanitize pass — Side-by-side compare loads two already-sanitized boards in memory. It is not an upload or server diff; just a second guard pass on both sides.
Myth vs. Evidence Fact-Check
Does the studio upload my board, CSV, or pasted JSON?
No. Work stays on this device. Nothing is posted to a server. Every load, paste, restore, undo and redo runs sanitizeDoc, then guardShape, guardChart and plainText.
What does sanitize do to JSON I paste or restore?
sanitizeDoc keeps a bounded name, shape list and chart. Unknown fields are dropped. Each shape passes guardShape; charts pass guardChart; labels pass plainText. Invalid docs are rejected, not rendered raw.
If I compare or load a recent board, does it leave this browser?
No. Recent boards are local. Compare and load still run sanitizeDoc first. guardShape, guardChart and plainText are not skipped on restore.
Can I open a coworker’s export without sending it off-device?
The file never uploads. sanitizeDoc and the guards run before render. That is not a virus scanner — only open files you trust. Studio stays sanitize-safe; the guards are not optional.
