WCAG contrast guidance Accessibility baselines for color and text on charts.
Org style guides / brand kits Palette and type rules may override studio defaults.
Data ethics / disclosure policies Source notes and truncation honesty belong with the publisher. Myths vs facts 3D always looks more professional → Perspective distortion often hurts comparison; flat encodings read cleaner. More ink = more insight → Chartjunk competes with the data signal. Studio export needs no review → Always check contrast, labels, and source notes before publish. Deeper FAQ Is the studio a full design suite replacement? No. It is a focused viz craft workspace with honest chart/diagram defaults.
Do scores crown the “best” chart? No. They are editorial browsing meters for craft dimensions.
Does studio guarantee WCAG pass? No. Defaults help; final contrast and semantics still need review.
Pie charts always bad? Often misused for many categories; small part-to-whole sets can still work with care.
Checklist
1 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. Important caveat Not a compliance stamp. Color, contrast, and data integrity still need human review before publication.
Editor depth Editorial meters compare craft clarity and classroom/studio usefulness — not “best chart” trophies. On VS pages, ask which encoding reduces lies under your data shape — not which looks trendier.
Deeper sources Grammar of graphics / perceptual encoding primers WCAG contrast documentation Tool-Lifes viz studio quality notes Important caveat Not a compliance stamp. Color, contrast, and data integrity still need human review before publication.

How Chart.js quick charts shows up here
Excel or Google Sheets and PowerPoint share this geometry. Keep one claim per slide; export SVG or PDF rather than a screenshot.
In Meta, Google and retail print, one number and one shape speak first. If Chart.js quick charts will not fit a banner, keep the number and show the chart on the landing page.
For lab reports and poster boards, pick the form that answers the rubric. Axes, units and a source line are what markers actually read.
