The Science of Infographics

Why do people love infographics?

Humans have been drawing pictures to communicate with each other for thousands of years—from pictograms on cave walls to Egyptian hieroglyphics to ideograms on modern signs (Figure 1-1). People love using pictures to communicate and tell stories because it’s hardwired into the human brain.

Infographics and data visualizations are all around us. We are surrounded by visual representations of information—charts, maps, icons, progress bars, signs, posters, diagrams, and online visuals (Figure 1-2). These are all examples of visual communication, but these are not all infographics.

The word infographic is used by people to mean many different things. In many cases infographics and data visualizations are considered synonymous, but in the world of an infographic designer they mean different things.

Data visualizations are the visual representations of numerical values. Charts and graphs are data visualizations and create a picture from a given set of data. Figure 1-3 shows the price chart of the S&P 500, the Nasdaq, and the Dow Jones Industrial Average since 1950. The reader can easily see the overall upward trend and the comparison between the three data sets. Including the volume chart beneath the price chart, this data visualization creates a picture using at least 80,000 data points.

It takes us only seconds to understand the long-term trend, to see the close relationship between the three indices, and to see the significant spikes and falls in the stock market. This visualization easily fits on one piece of paper, a computer screen without scrolling, or a presentation slide. Seeing the entire data set on one page, we can understand the data quickly and with little effort.

This is an efficient way to communicate data. Data visualizations can be very space efficient by visualizing a large set of numbers in a small space. By designing a visualization that displays all of the data within the readers’ field of view, this enables us to see the entire data set with minimal eye movement without scrolling or flipping between pages.

If we looked at a spreadsheet with 80,000 values instead, how long would it take us to get a general understanding of the market?

In 2001, Dr. Edward R. Tufte, one of the pioneers of modern data visualization and professor emeritus of political science, statistics, and computer science from Yale University, clearly explained this phenomenon when he stated, “Of all methods for analyzing and communicating statistical information, well-designed data graphics are usually the simplest and at the same time the most powerful.”^[1]

This screen shot (Figure 1-4) from the StockTouch app on an iPad is another example of a good data visualization design. The top 100 largest U.S. stocks are shown from nine different market sectors. In this view, the companies from each market segment are organized in a spiral pattern from largest (in the center) to smallest. Each stock is color coded based on its stock price performance over the prior 12 months, but the time period is adjustable with the slider on the right. The shades of green show stock prices that have increased, and shades of red show prices that have decreased.

Whether it’s a new definition or an additional definition of the term infographics, its use now implies much more than just a data visualization. Up until recently, a common definition for infographics was simply “a visual representation of data”; however, that definition is outdated and is more indicative of data visualizations. Originally derived from the phrase information graphics, infographics was a term used in the production of graphics for newspapers and magazin...
