This course gives an introduction to the creation of graphs for effective communication and data exploration. Participants will be able to design graphs according to the desired function while considering the conflicting aims of design (effectiveness/expressiveness, legibility/depth, …). Practical application of the theoretical knowledge – preferably with own data – is an integral part of the course.
Theory:
•Components of a graph
•Visual variables (length, area, colour, …) and their effectiveness
•Functions of graphs
•Graph types and their effectiveness
•Conflicting design goals
•The physiology of vision
•Colour
•Data mining, critical assessment of data sources
•Properties of data
•Data integrity
•Data reduction and transformation
•Exploratory data analysis
•Visual statistics
•Pictograms
•Visual storytelling
•Copyright licenses
•File types for graphics
Practice:
•Creation of an A3 infographic, using own or external data
•Constant refining of the infographic and its graphs by implementing new knowledge
•Rules of thumb for scientific posters and slides
•Peer feedback, critical assessment of alterations to the graphic/graph
•Free-hand drawing for quick sketching
•Vector and pixel based drawing software
•Graphing software
