Where do people tweet during the Taksim-square protests in Istanbul?

Small test using 48 hours of geolocated tweets in Istanbul, gathered during the protests at Taksim-square in Istanbul. Although there is a clear density at the square, it is even more obvious that people tweet most from the bars and clubs along the Bosporus, showing a distinct border of land and water and even the bridge over the Bosporus. Tweets are color-coded for the time they have been send. This is a first iteration of a series, which will be elaborated further.
