The importance of being axonometric

With digitalised data and processes making transmission of knowledge increasingly abstract and intangible, information design has become crucially urgent — Michael Stoll, a university teacher and collector, explains the principles and scale of this discipline. An interview from Augsburg by Marco Ferrari, Elisa Pasqual

For years Michael Stoll has been collecting and publishing paper material online that would otherwise be lost. His Flickr account now contains more than 100 sets of images personally scanned from his archive: a panorama of information design spanning from the early 20th century to the present day, including user and instruction manuals, illustrated reports, urban representations and maps. This heritage is also an obstinate record of the power of information. When we arrived at the Augsburg University of Applied Sciences, one of the three universities at which he teaches Media Theory and Information Design, he promptly took us on an extensive tour of lecture theatres and workshops, while describing the work of his students and how the goal of his teaching is to produce designers who appreciate the autonomy of all forms of knowledge.

Domus: When did you start your collection?
Michael Stoll: It all began when I encountered the danger of paper disappearing one day, overwhelmed by the digital. If you can hold something in your hands it gives you a more holistic impression of the topic. When I started collecting I also discovered how much interesting and useful stuff had already been invented. As a result I decided to focus on a certain time span because it started to get too expensive. I have to thank my wife for not complaining about my huge collection, as a lot of private money runs into it.

Given these premises, it's peculiar that you made everything you laid your hands on available to the whole digital community by publishing it online. The Internet was also where you found and bought most of your materials, is that right?
I actually found some of my pieces in flea markets or by accident. But, yes, most of the stuff was sourced on the Web. I begun to publish it because information design lacks a valid theory behind it, as well as an overview of its history.

Your online collection on Flickr counts more than 100 sets of pictures. Do you have a favorite?
I'd choose the 1953 World Geographic Atlas. Everybody is impressed by its quality and its sheer weight, but there's more behind it. It was published with Herbert Bayer's Bauhaus knowledge, and it anticipated the educational modernism of the 1960s and '70s. For me as German, the story has another twist: although Herbert Bayer once worked for the Nazi-regime, he later had to leave Germany. It's a warning that the free flow of knowledge and democracy should go hand in hand. We shouldn't forget this.

Where would you place the historical beginnings of information graphics?
I would start with early cave paintings. Seen from today's perspective, they unify visual storytelling and artistic beauty. In other words, art and science originally belonged together, and their division is a relatively recent phenomenon. Although there aren't many examples of infographics remaining from the following centuries, I'd stop talking about the beginnings by the year 1350, when the French bishop Nicole Oresme (1323-1382) "invented" the bar chart. Then, in 1493, Hartmann Schedel printed his famous book Schedel'sche Weltchronik, which explained how God spent the first seven days creating the world. Leonardo da Vinci's technical drawings were tools to clear up thoughts and convey knowledge in a visual manner. In 1786 William Playfair made extensive use of infographics, explaining economic matters in his Commercial and Political Atlas. Finally, in 1869 Charles Joseph Minard created an impressive diagram about Napoleon's march to Moscow and back.

As information design doesn't have a structured theoretical background, how do you organise your material? Have you created your own personal taxonomy?
I tried to face this problem—the fact that information design doesn't have a valid taxonomy—with my diploma back in 1991. My idea was to invent a taxonomy that helped journalists and information graphic artists to communicate on the same level. A taxonomy cannot relate to the aspect of visualisation—pie charts, bar charts, explosion drawings—which could disappear from time to time, but rather to the information behind the visualisation. All visual means that try to explain something to you can be placed into one of three groups. The first group is based on numbers, statistics and relations between sizes (data graphics); the second group is made up of objects (group system graphics); and the third one consists of spatial data like maps (spatial graphics). As these fields often overlap, it's also important to consider the borders between information design and, for example, illustration. I always say that information graphics has a strong appeal in the way it can clear up stuff and convey knowledge. Compared to examples such as illustration, information graphics always seeks to increase the knowledge of the reader, like every design process.

This basic taxonomy seems to be very straightforward and effective.
The common idea behind numbers is to make relations more concrete by applying abstract quantities to concrete visual forms. The interesting thing is that an object graphic works the other way around. Richard Saul Wurman's book Medical Access, from the Access series he wrote in the 1980s, gives a step-by-step description of surgery for the average reader. The problem with this kind of image is that it risks looking totally gross: blood all over the place and people with knives trying to cut something out of your stomach. You can't actually show that sort of thing to average people.

There is also the problem of showing abstract operations, such as psychiatry or other complex things that readers can't imagine since they don't have the necessary knowledge.
That's right. The idea behind system graphics is not to make things more concrete but to make them more abstract. So by transforming photographs of surgery or forensic entomology into a graphic, you make them consumable. A translation into a vector graphic helps to look at things that would otherwise shock you. Only drawing gives you the ability to modulate details within one image. When you take a photograph you have the possibility to bring one object into the centre, but with an infographic you can show how it works internally.

It's about creating a metaphor that people know how to decode. But it also seems crucial to make people aware of the method you're using to present information.
In infographics we speak of "ensuring perception". In other words. we have to ensure that what we show is perceived as intended. I normally ask students to draw me a human liver on the white board, and everybody always says, "Oh, no! I can't draw a liver." I can't draw a liver either, but I can show you how an information designer would do it. He would simply draw something that is supposed to be a liver and then he would label it. The interesting thing is that these labels ensure the perception of the shape. In most cases it can work the other way around, too, when you show an object that doesn't have a name yet. It's like a layer above the information itself.

What happens when the users come from different cultures?
Although I think the visual is a rather global language, its borders are set by cultural backgrounds. Information design is not the main target in communicating on a global level. The question "who will read our graphics?" is a very important one, and it has to be answered from the context in which the graphic is published. I don't think we'll all end up speaking the same visual language, as that would mean that everyone on earth had gone through more or less the same socialisation process.

Is the recent proliferation of infographics reducing the effectiveness of the visualisation itself? And to what extent can aesthetics affect the readability of data?
Choosing a visualisation purely on the basis of its beauty can be a huge problem. We need to avoid design for design's sake. Aesthetics is a method of presentation without distracting elements. The aesthetics of infographics can't be defined per se, because in most cases it appears in the context of a newspaper, a magazine, a website or a cityscape, with which it has to appear as a single integrated system. But I think this discipline is still in its early stages and standards have yet to evolve.

Newspapers are full of infographics nowadays. People have less and less time to read, so flows of information have become crucial even if invisible.
Many people think that acquiring data is a voluntary task. But in today's information society, the amount and quality of knowledge you hold is essential for your private success. If you're developing strategies to learn fast, you'll probably go further than people who avoid doing that. It's not just you voluntarily pushing yourself; it's also society pulling a required amount of knowledge from you. Conveying knowledge is a deeply democratic process, but it's also important that the readers understand it.

What about maps?
I collect axonometric cityscapes. I began to focus on them when I found a map of Augsburg by Hermann Bollmann. I like these maps because they show escaping flatlands and they're easy to read. Interestingly, there are very few artist doing axonometric cityscapes nowadays.

In perspectives the presence of the viewer is very strong, while an axonometric view has no centre point at all. We could say it's more democratic.
In axonometric maps you're above the scene, not part of it, and when you don't have a vanishing point everything looks "over-parallel": everything is clear, clean and in the same light. Perhaps it's more of a communistic than democratic view of a scene. Often axonometric maps look more beautiful than reality itself.
