Juan Velasco is an award-winning art director of the National Geographic magazine. He was a graphics reporter for the Spanish newspaper El Mundo in Madrid, and later became the graphics art director for The New York Times from 1998 to 2001.
Velasco owns a business called 5W Infographics, from which he has done graphics redesigns for newspapers such as Le Monde in France and Tribune de Geneve in Switzerland.
The Rise of Interactive Graphics (Chapter 9 of The Functional Art by Alberto Cairo) talks about the discovery of interactive visualizations and how they began in the multimedia world.
I enjoyed reading this chapter because I could feel Professor Cairo’s excitement through his words. For example, when he referred to the feeling he got when he was creating the interactive graphic below, back when working for El Mundo in Spain.
Alberto Cairo’s Chapter 7 of The Functional Art (Images in the Head) taught me how images we have in our heads may often be a burden when reading and analyzing infographics. That’s why an infographic must have the appropriate designs and features and must be well thought out before putting them out in the world for people to analyze and interpret.
In Chapter 5 of Professor Cairo’s The Functional Art (The Eye and the Visual Brain), Prof. Cairo explores the role the eye plays in the way we see and how people understand infographics.
Antonio Damassio said the following: “The human brain is is a natural born cartographer.” Therefore saying, we humans were born with the ability to understand visualizations and different types of graphics.
Uncertainty and Significance (Chapter 11 of The Truthful Art by Alberto Cairo) talks about the margin of errors. According to Cairo, the margin of error is very important to the final result and could greatly affect the information presented and its accuracy.
In the example seen below, Cairo shows the difference in percentages between the people who do not want Catalonia to become an independent state, and the people who do. It also shows the margin of error (depicted on the right), which is more or less 3 percent.
