Display quantitative information
Help the viewer reason from evidence. Prioritise truthful encoding and useful comparisons over cosmetic minimalism. Preserve the package's Tufte-informed methods without turning data-ink or any other maxim into an automatic verdict.
Work from the analytical task
- Identify the comparison or decision: lookup, trend, relationship, distribution, composition, geography, uncertainty, or monitoring.
- Inspect grain, units, denominator, groups, missingness, time spacing, transformations, sample size, and uncertainty before plotting. Separate observations from summaries.
- Choose a display for that task using display selection when needed. Establish intentional aggregation and ordering explicitly.
- Audit scales and encodings before aesthetics. Check actual data bounds, baseline, transformations, temporal spacing, omitted values, and uncertainty against source data.
- Deliver the requested chart, code, specification, or critique. Verify the output itself rather than assuming a successful plotting command preserved its meaning.
