I follow a subreddit called “DataIsBeautiful.” It’s about data visualization, which I love because it helps numbers to tell their story, and numbers don’t lie.
People can use them to distort truth by the data they leave out, the scales they use or their statistical methods (I think it might be smarter for us to teach more statistics and less algebra). The editorial notes (in blue & red) indicate an obvious agenda behind this display, which, in itself would not disqualify it. But this author committed the deadly sin. He didn’t include the source for his data.
