I took Dr. Cairo’s data visualization class in the past. He is an interesting and knowledgeable scholar in his fields. Be sure to check out this interview about his favorite infographics.
‘The more people that start creating visualizations, the more examples we will see. We will also see the amount of crap increase, that is obvious. But as Theodore Sturgeon said many years ago: ’90 percent of everything is crap.’ If you increase the amount of things, you will have more crap, but you will also increase the 10 % of great things, which is what everyone wants. I don’t mind that there are a lot of bad visualizations, as long as the amount of good visualizations also increases.
