Different US Election Maps Tell ‘Different Versions of the Truth’

Issie Lapowsky, writing for Wired:

Conservatives replying to Yingst’s tweet interpreted the expanse of red as proof of their party’s dominance throughout all levels of government. Liberals viewed the map as a distortion, masking the fact that most of that redness covers sparsely populated land, with relatively few voters.

In reality, both sides are right, says Ken Field. A self-proclaimed “cartonerd,” Field is a product engineer at the mapping software company Esri and author of a guidebook for mapmakers called Cartography. The problem, he says, isn’t with people’s partisan interpretation of the map. The problem is believing that any single map can ever tell the whole story. “People see maps of any type, and particularly election maps, as the result, the outcome, but there are so many different types of maps available that can portray results in shades of the truth,” Field says. “It’s a question of the level of detail that people are interested in understanding.”

Really interesting examples of data visualization in this piece.
