After visiting six parks in 2011—Atlanta's Piedmont Park, Copenhagen's Rosenborg Castle Gardens, Amsterdam's Vondelpark, Berlin's Tiergarten, Brooklyn's Prospect Park, San Francisco's Golden Gate Park, and New York's Central Park—graphic designer Mikell Fine Iles realized how critical a city's park is to growing metropolitan populations. "Clean air, space to play, relax, exercise, wildlife sanctuary, cultural and educational institutions and activities, social interactions, family BBQ’s and picnics, and water irrigation are just a slice of the positive effects on a city that large parks provide," Iles writes. To compare the parks' qualities, Iles created six infographics that put size, shape, visitor numbers, and dates of inception side by side. How does your local park measure up? •
