Where did Berliners vote more for the left (Linke) than for the right-wing populist (AfD) in 2017?

Election results on an election district ("Wahlbezirke") level from the German federal election 2017. Districts are colored with either an AfD blue or a Die Linke pink, depending on who got more votes ("Zweitstimmen"). The darker the color, the higher the ratio difference.
