I stumbled upon a quite simple and direct visualization, and also a new word- ISOTYPE.
(just a quick explanation of the word : it stands for the International System Of TYpographic Picture Education, which is a visual language for capturing quantitative information in pictograms, the graphical style is very common nowadays however I can only imagine how refreshing it would’ve have been when it was first introduced!)
the image above isn’t very special, however last week when researching about experts and pioneers of dataviz, I thought of my assigned expert Edward Tufte, and I wanted to apply his formula of “the Lie Factor”.
so each horizontal line represents 10 years increase, however the first line is 9.8 inches, and the last line is 9.5 inches. (OMG this formula is more confusing than I expected it to be! laugh all you want, but it took me hours to get this calculation right!) According to Tuftte, the lie factor must be between 0.95 to 1.05 to be considered a “true” visualization.
So, the lie factor of this graphic is approx. 1! Which makes it a pretty accurate graph. ;)
*side note about ISOTYPE-ing: thinking about the ways that ideas might be put to use to engage the public with the social and political aspects of contemporary science. I didn’t go very far with those thoughts, but it might be something to think about again.
