Wilson Andrews, The Washington Post’s information designer, discusses his data visualizations and the progress of the field in a Forbes interview. “The kinds of graphics that are now being done, especially online, are on another level than what was being produced several years ago,” he says. “Long form journalism is just as important as it ever was, but often long form pieces are greatly enhanced by smart and clear data visualization.” He says that he starts with the simplest possible design, only adding movement and interactive elements if they will help people understand the information. Examples of his work are in the interview. Related: WNYC’s John Keefe finished up his New York evacuation map as he rode the subway to work last week.
