Data-ink in 1983: Encoding — Section 1011: Encoding

Briefing 1011 for Data-ink aligns condition “Encoding” with reference value 1983 on the ground. data-ink · beat 0 · Axis names, units, a source line. Markers read them. Keep Data-ink with “Encoding” and 1983 from 1983. Start with a mind map if you must; submit a figure that reads like Data-ink.

Every pixel should earn its keep — Tufte’s test for reports, and a warning against cute ads. Data-ink encodes values as the share of ink that represents data versus decoration. Edward Tufte, The Visual Display of Quantitative Information, 1983. In reports, ads and assignments it fits auditing slides, dashboards and science figures. Skip it when a poster that must shout from three metres — ads may keep some junk on purpose.

This page gathers anatomy, fit, craft, failure modes and work / ads / school recipes for Data-ink. When the story is: auditing slides, dashboards and science figures. Skip it in cases like: a poster that must shout from three metres — ads may keep some junk on purpose. Edward Tufte, The Visual Display of Quantitative Information, 1983

the share of ink that represents data versus decoration Yes if one claim is visible at a glance in Meta, Google and retail print; otherwise link to a full figure. Yes for lab reports and poster boards if axes, units and a source line are present. Excel or Google Sheets or PowerPoint; export SVG/PDF. Rather than relying on simplified league tables or slogans, keeping the primary Data-ink section open beside benchmark 1983 (“Encoding”) gives operators and readers a verifiable decision trail.

Read Data-ink as 1983, “Encoding,” and 1983. A bar with no unit is not those three. Keep Data-ink with “Encoding” and 1983 from 1983. 19831983

Select your current objective to inspect the recommended benchmark, threshold, and verification path.

Leave the current chart type. If a guard warning is showing, fix that field before export.

5-Step Execution & Verification Playbook

  1. Paste stays on this device — JSON you paste or restore never uploads. The studio keeps work in browser memory and local storage only.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
06

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.

Domain Jargon & Terminology Decoder

State the question the viz must answer.
2
Prefer position/length encodings when comparing.
3
Run a contrast check before publish.
4
Open studio early; iterate marks, not themes.
