Isarithmic maps are essentially topographic or contour maps, wherein a third variable is represented in two dimensions by color, or by contour lines, indicating gradations. I had never seen such a map depicting political data — certainly not election returns, and thus sought to create them.The isarithmic depiction does an excellent job of highlighting several broad patterns in modern U.S. political history. 

This animated interpretation accentuates certain phenomena: the breadth and duration of support for Roosevelt, the shift from a Democratic to a Republican South, the move from an ostensibly east-west division to the contemporary coasts-versus-heartland division, and the stability of the latter.

More broadly, this video is a reminder that what constitutes “politics as usual” is always in flux, shifting sometimes abruptly. The landscape of American politics is constantly evolving,  as members of the two great parties battle for electoral supremacy.

Millionaire Doug Tompkins wanted to save a rainforest, so he went out and bought one in Southern Chile. Many Chileans though are not so keen on his philanthropy and regard him with suspicion.

The self-made millionaire of the Esprit clothing company, Doug Tompkins, now languishes in an Eden of lush forest, deep rivers and abundant wildlife. His massive reserve, Pumalin Park, is an oasis of biodiverstiy. Conservative politician Jaime Orpis regards the swath of land controlled by Tompkins as a threat to national security. His reserve is a strategic 100km long corridor from the Argentine border to central Chile. For a nation still on the periphery of economic success having such a staunch anti-developmentalist tying up resources is also deeply irritating. Many would prefer him to take his high ideals back home. Tompkins though, came to Chile with a dream and despite the knocks he's staying until the government agrees to protect his park themselves.
