Data Visualisation

According to Friendly M. and Denis D., ‘data visualisation’ is “the science of visual representation of ‘data’, defined as information which has been abstracted in some schematic form, including attributes or variables for the units of information”. In fact, the main purpose of data visualisation is to communicate data by representing it in an effective and clearly way, by using for example statistical graphics, maps, plots, tables, diagrams, information graphics, etc. In consequence, data visualisation subsumes two main focuses, on the one hand statistical graphics and on the other thematic cartography. Furthermore, it allows the user to visualise the data in a more effective way, so that the data is more understandable and usable in order that the user can reason and analyse it. To it sum up, data visualisation is the graphic portrayal of quantitative information.
