Infographics

What it is

An infographic explains something through a planned relationship between words and visuals. It may combine a chart, timeline, map, illustration, diagram, and a few short captions. Its value comes from clarifying a question, process, or comparison—not from decorating a page with icons.

An infographic differs from a single data visualisation in scope. A chart can let readers inspect one dataset; an infographic may lead them through context, evidence, and implications. Some infographics have no quantitative data at all. In either case, visual choices must preserve the meaning of the source material.

Define one reader journey

Start with the audience and the action or understanding you want to support. Write a one-sentence takeaway, then list the questions a reader must answer to reach it. This reveals the likely sequence: orientation, essential evidence, explanation, and consequence. If the piece tries to answer five unrelated questions, separate them or choose a stronger central thread.

Choose a format from the viewing condition. A printed wall graphic can invite exploration; a mobile graphic needs a narrower path and readable details. A social crop may need a focused claim that points to the full explanation. Plan these adaptations before building a dense master layout.

Research and structure the evidence

Trace every claim

Collect original data, dates, definitions, and source notes. Check whether values are comparable: do they cover the same period, geography, population, or measurement? A percentage without a denominator or a trend without a baseline can mislead even when every number is technically correct.

Keep a working source table linking each visible claim to its evidence. Separate observed facts from estimates, interpretations, and recommendations. If uncertainty matters, show it in language and form rather than hiding it in a footnote.

Sketch the information architecture

Arrange the claims as a rough storyboard. Decide which ideas need precise comparison, which need a process diagram, and which can be stated in plain text. Use arrows only when they represent direction or causality; proximity and grouping may communicate a relationship more honestly.

Build a clear entry point and reading order. The headline should state the subject, the primary visual should carry the main idea, and supporting details should answer predictable follow-up questions. This hierarchy should still work when the piece is viewed briefly or at a reduced size.

Choose visual forms carefully

Use charts when the relationship is quantitative and exact enough to justify a chart. Use diagrams to show parts, sequence, or connections. Use illustration to make an unfamiliar object or setting recognisable. Resist replacing comparable values with decorative pictograms of different sizes; apparent area can distort the comparison.

Colour can group topics, highlight a finding, or distinguish categories, but it should not be the only carrier of meaning. Label graphics directly where possible, and check contrast at the size people will actually see. Establish a modest type hierarchy so readers can tell a title, claim, label, and source apart.

Review with fresh eyes

Ask someone unfamiliar with the subject to explain what they think the graphic says, where they started reading, and which claim they would repeat. Misreadings point to a hierarchy or wording problem, not simply a need for more decoration. Check every figure and label against the source table after design changes; a cropped graphic can silently lose context.

Test the output in its real medium. On mobile, avoid tiny labels and provide an accessible text summary or table when detail cannot fit. In print, inspect final size, colour, and viewing distance. Deliver an editable source, a publication-ready export, alt text or a text equivalent, and a record of sources and update dates.

Common mistake

Choosing a visually dramatic form before knowing what must be understood. A restrained diagram with a clear sequence can outperform a crowded poster of impressive but disconnected facts. Begin with the reader’s question and let each visual element earn its place.
