What is nice is that often the presented material is backed up by hints to literature (e.g. that the visualization presented, and the best practices for using it, are backed up by a scientific study about how to properly use it, etc.)


Weekly lectures with well prepared slides. Material is presented rather slow (not in a bad way) and thoroughly [imho].

Different "grading packages" available: Either do:

  • two practical exercises with datasets, visualize and analyze data and submit reports + presentation in the end.
  • 1 practical exercise with dataset, as above. Then a final oral exam.

Attendance is checked with list, depending on grading package a certain number of attendances (5 to 7) can earn you points toward your final grade.

Benötigte/Empfehlenswerte Vorkenntnisse

Knowledge of Python, especially Pandas, and visualization tools such as matplotlib, seaborn, etc., is necessary. If assignment 2 is selected, then usage of a tool or library for interactive data visualization is also required (or needs to be picked up).

Some statistical knowledge is also required, and basics of visual data analysis.

  • Assignment ("Lab") 1: Given data-set, compare computational and visualization methods. Tasks: Cluster analysis. Check for correlations. Compare groups of variables. Written report of at least 3 pages is to be submitted.
  • Assignment ("Lab") 2: Search your own large data-set. Explore, get insights. Then either: make a Dashboard for exploration, or: write report about analysis of 6 different visualizations, i.e. a literature review/survey.

  • Assignment 1: a few hours, to familiarize yourself with the data, the tasks to perform, and the tools you need. Depending on your skills in tools for visualizations (some plots have to be created and analyzed) as well as methods for clustering (e.g. scikit-learn), your milage may vary. Then a little more effort for writing min. 3 page report (including figures where appropriate).
  • Assignment 2: [can't really say, I switched to taking the exam rather than doing the assignment 2, as I coulnd't afford taking the time; it seems that taking the exam is much less effort than doing the assignment, but that is only my humble opinion. Please add other experiences]
  • Exam preparation: 2-3 days (without attending the lecture: most of the stuff (diagrams) has been discussed in other courses (charts, perception, ...), for some other topics (AI Vis, charts/apps, ...) the referenced papers have to be read since the slides are bit sparse)


Slides are available from the classe's web page, see link above.
