Here you are a little apperitive of his answers:
"When I was in the graphics director job in the newsroom, I urged the staff to experiment with exotic charting form and complex data sets. In this job, I do my best to make the charts as simple as possible. My thinking is (and the response has been) that my readers are not impressed by visual tricks. They want strong points that are easy to grasp."
