Iconic data visualisations do more than present information: they make patterns visible through deliberate choices about what to include, how to encode it and whom to persuade. These eight examples range from eighteenth-century timelines to an interactive bubble chart. “Iconic” is an editorial judgment, not a fixed or authoritative ranking.
What makes a data visualisation iconic?
A memorable graphic often gives a complex relationship a form people can read quickly: lifespans lined up on a timeline, deaths plotted against water pumps, or an army’s changing size drawn as a narrowing band. But no chart is a neutral window onto facts. The selection of data, the scale and visual encoding, and the intended audience all shape what viewers notice—and what they may miss.
The examples below answer different questions and serve different purposes. Some were designed to persuade, others to organize or explore information. Their influence does not make them flawless: readers should ask what is included, how quantities are represented and whether the display simplifies geography or groups observations in ways that matter.
Eight iconic examples of data visualisation
1. Joseph Priestley’s Chart of Biography
Priestley’s Chart of Biography aligns the lifespans of notable people along a shared timeline. Its central question is visual: which people lived at the same time? Rather than making readers compare separate dates mentally, the design makes overlap and succession visible at a glance.

- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
The chart’s scope is shaped by whom Priestley selected as notable. It is a useful timeline, but not a comprehensive record of everyone who lived in the periods it covers. Its lasting lesson is that a timeline can reveal simultaneity while also reflecting the choices behind its categories and subjects.
2. Joseph Priestley’s New Chart of History
Priestley’s New Chart of History applies a related timeline idea to the duration and overlap of empires and cultures. It helps readers see political entities as periods that coexist, begin and end, rather than as a simple sequence of names in a list.
As with the Chart of Biography, the selection and framing matter: the entities represented reflect the chart-maker’s scope. The two works are distinct examples of using aligned time to make overlap legible, but they organize different subjects—people in one, political and cultural histories in the other.

3. William Playfair’s wheat-price and wages chart
In a chart published in 1786, William Playfair compared wheat prices and wages from 1565 to 1821, with monarchs’ reigns placed above the time series. That arrangement invited readers to consider how wages related to the cost of a staple food across a long span of history.

The monarchs’ reigns add historical context, but the comparison should be understood as this chart’s particular design, not as a claim about every diagram in Playfair’s atlas.
4. John Snow’s Broad Street cholera map
During the 1854 cholera outbreak in Soho, London, John Snow mapped deaths alongside the locations of water pumps. The concentration of deaths around the Broad Street pump helped investigators examine a possible waterborne source. The map’s key strength is spatial: location can expose a cluster that is harder to see in a table of individual cases.

The map supported an investigation; it did not, by itself, prove causation or establish that one intervention alone ended the epidemic. Its enduring value is methodological: plotting observations in place can generate and sharpen questions about how exposure and outcomes relate.
5. Florence Nightingale’s polar-area mortality diagram
Nightingale’s “Diagram of the causes of mortality in the army in the East” represented mortality during the Crimean War. Its polar-area form makes it visually distinctive, while its purpose was persuasive: the diagram helped argue for sanitary reform. Nightingale used the term “coxcomb” for her diagrams; “polar-area chart” describes the visual form more technically.
The graphic shows how form can serve an argument, particularly when readers are accustomed to tabular presentation. As Alison Hedley writes in her 2020 article for Significance, “But what made Nightingale’s graphs particularly iconic was their powerful use of visual rhetoric to make an argument about data.” The chart’s persuasive force is part of its significance, not a reason to treat its visual encoding as self-explanatory.

6. Charles Joseph Minard’s map of Napoleon’s Russian campaign
Published in 1869, Minard’s flow map depicts the French army’s campaign of 1812–1813. Band width represents troop numbers; the bands’ positions and direction trace the campaign, while dates and a temperature series add context. It brings movement, changing force size and environmental information into a single graphic.
The map is a synthesis, not a precise route guide: its flow geometry is schematic, so individual band segments should not be read as exact geographic paths. To interpret it, distinguish what each encoding represents—width for troop numbers, position and direction for the campaign, and the accompanying dates and temperature series for context.
7. W. E. B. Du Bois’s Paris Exposition charts
At the 1900 Paris Exposition, a series of charts, maps and diagrams presented aspects of Black Americans’ lives and conditions to an international audience. The works belong in their historical and political setting: they used visual evidence to make information about Black life visible within a major exposition.

This is a collection, not one chart, and it should not be collapsed into a single artifact or attributed wholly to one individual without evidence. Its significance lies in the series’ use of varied visual forms and its public purpose in that setting.
8. Gapminder’s animated bubble chart
Gapminder’s familiar animated form can place measures such as income and life expectancy on the axes, use bubble area for population and color for region, and let viewers follow observations over time. It makes broad patterns approachable by putting several variables into one view and showing how observations change across time.
Animation and interactivity do not remove the need for careful reading. The measures chosen, the scales used and the animation itself influence which changes stand out. Viewers should treat the display as a way to explore patterns, not as a substitute for asking how the variables are defined and represented.
Quick Recap
What these famous charts teach us
- Encoding carries meaning. A timeline makes overlap visible; a map puts outcomes in place; a flow band uses width to represent quantity. Read the visual key before drawing conclusions.
- Place can reveal patterns. Snow’s map shows how mapping deaths alongside pump locations can focus an investigation on a spatial cluster.
- Purpose affects presentation. Nightingale’s diagram and Du Bois’s exposition series were made in particular historical and public contexts. Persuasive graphics deserve attention both for their evidence and for the argument they were designed to make.
- Every display has boundaries. Priestley’s selections, the variables and scales in an animated chart, and Minard’s schematic flow geometry all shape what a viewer can infer.
- Iconic does not mean infallible. Ask what is included, what is omitted, how quantities are encoded and whether aggregation or visual simplification could change the impression.
