In Summary on Data Visualisation

  • Think carefully about exactly what it is, you want to communicate with your visualisation

  • Remove redundant information

  • Be honest and show your data

  • Less is more, do not cram 3 plots into 1

  • Do not make a fancy, but information deprived plot

  • Think about colour choice - Separation, but also quite a few people are colour blind

  • Today is meant as in intro, data visualisation will be an integrated part of the rest of the course

10 minute break and the it is time for exercises…
