LESSONS FROM DATA JOURNALISM

A little bit of history

"As knowledge increases amongst mankind, and transactions multiply, it becomes more and more desirable to abbreviate and facilitate the modes of conveying information from one person to another, and from one individual to the many."
        

William Playfair, 1786

"Everything that can be expressed in numbers can be represented by lines."
        

John Playfair
