The course has two main purposes. The first purpose is to introduce the main data visualization techniques, which, when properly used, can allow both the visual analysis of the data, in order to discover the relevant information and relationships they express, and the effective dissemination of the obtained results. For each type of chart, its main features, functionalities and (appropriate) uses will be presented. The second purpose of the course is to provide the basic concepts for the design of "information dashboards"; they are (interactive) applications allowing a (in real time) monitoring of a system, through the (interactive and real-time) visualization of a set of system performance metrics.
Expected learning outcomes
After the course the student must be able to choose the proper graph depending on the data to be analyzed or displayed. He must be capable of designing a visually informative information dashboard for system performace assessment
