Cartography of the Barceloneta market in Barcelona. It is the result of the study of the relationship between three attributes; time, non-space of the square and market and people’s opinion about the stops through a study on Tripadvisor comments and ratings. The three attributes are divided into three languages; height and color code in the case of the opinions, opacity to represent the non-space (space through which there is no passage of people) and density in the case of the routes that occur inside and outside the square.
