Examples of these streams are traffic, pollution, social media activity, citizens dynamic, etc. which show us what, where and when is happening in the city. The purpose of this paper is to apply different types of glyphs for showing real-time stream evolution of data gathered in the city. The use of glyphs is intended to make the most out human capability for outperforming in detecting visual patterns.
