Chart selection depends on your data structure and communication goal. This Skill provides a design-decision framework that matches chart types to data relationships—comparing values, showing trends, revealing distributions, or displaying hierarchies—ensuring your visualization serves its intended task truthfully and clearly.

Truthful visualizations encode data accurately without distortion, use color redundantly so information isn't lost for colorblind viewers, and include annotations guiding interpretation. This Skill applies mandatory accessibility and truthfulness checks across dashboards, reports, and infographics to prevent misleading encodings.

Color strategy balances aesthetic appeal with functional clarity and accessibility. This Skill guides palette selection, ensures sufficient contrast for visual impairment, employs redundant encoding beyond color alone, and validates that your chosen colors support rather than obscure data patterns in multi-chart layouts.

Yes. This Skill applies to any data-visualization task requiring design rigor—dashboards, reports, infographics, and narrative visualizations. The four-element design-decision framework works across formats, helping you encode data clearly, select appropriate visual marks, and annotate insights to guide viewer interpretation.

Validate data correctness and preparation first; this Skill assumes clean, well-structured input. Pre-work compliance prevents implementation-first antipatterns, ensuring design decisions are grounded in accurate data and clear communication goals rather than visual polish applied after the fact.
