New data science method makes charts easier to read at a glance

Science Daily  October 18, 2018 A team of researchers in the US (Columbia University, Tufts University) has developed a new method — “Pixel Approximate Entropy” — that measures the complexity of a data visualization and assigns a “visual complexity score”. The system automatically simplifies or summarizes charts that would be hard to read on their own. They modified a low dimensional entropy measure to operate on line charts, and then conducted a series of user studies that demonstrated the measure could predict how well users perceived charts… read more.
