When a brand team in Central opens a survey readout, they rarely start with the methodology appendix. They look for the one chart that answers whether awareness shifted, whether a claim landed, or whether a segment behaved differently from last wave.
We keep base sizes on every chart, not only in a glossary. If a cut drops below a usable sample, we say so beside the bars rather than hoping someone notices the footnote three slides later.
Axis labels stay concrete: “Share of respondents who tried the product in the past three months” beats “Usage.” Percentage points are named as points when comparing waves so nobody confuses them with percent change.
Colour does one job at a time. A highlight colour marks the brand or the wave that matters; everything else sits in a calm neutral so the eye is not asked to invent meaning.
Before a deck leaves our desk, we ask one colleague who was not on the project to paraphrase the chart aloud. If their paraphrase misses the research question, the label is still wrong.
