If you only read one thing
Match the question to an encoding - comparison, trend, part-to-whole, correlation - before opening any tool.
Key takeaways
Data-to-chart decision encodes values as task type mapped to mark and channel (length, position, angle, color). Bertin semiology; modern chooser guides and grammar-of-graphics tools. In reports, ads and assignments it fits first 60 seconds of any report, ad claim or assignment figure. Skip it when picking a chart because it looks fancy in the template gallery. This page gathers anatomy, fit, craft, failure modes and work / ads / school recipes for Data-to-chart decision.

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.

How Data-to-chart decision 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 Data-to-chart decision 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.

Frequently asked questions When should I pick Data-to-chart decision? When the story is: first 60 seconds of any report, ad claim or assignment figure.
When should I avoid Data-to-chart decision? Skip it in cases like: picking a chart because it looks fancy in the template gallery.
Who invented or popularised it? Bertin semiology; modern chooser guides and grammar-of-graphics tools
What does it encode? task type mapped to mark and channel (length, position, angle, color)
Is it OK in ads? Yes if one claim is visible at a glance in Meta, Google and retail print; otherwise link to a full figure.
Will a teacher accept it? Yes for lab reports and poster boards if axes, units and a source line are present.
Which tool? Excel or Google Sheets or PowerPoint; export SVG/PDF.
How do I keep it accessible? Do not rely on hue alone. Label directly and check greyscale.
