Johanna Schmidt

This course page describes the lecture of Wintersemester 2023/2024. See list of other semesters.


All information about the lecture (Zoom links, slides, etc) can be found on TUWEL.                 
Please post all questions about the lecture in the TUWEL forum.


The VU Visual Data Science will discuss how data scientists can apply visualization and Visual Analytics techniques in the data science workflow. The lecture will start with a theoretical introduction to visualization and Visual Analytics concepts. The second part of the lecture will deal with the practical application of Visual Data Science, namely the integration of visualization in the data science workflow, selection of charts, and a comparison of current applications and libraries. The lecture concludes with the late-breaking research topics of trust in visual interpretation and how to combine AI methods and visualization.


Important information about the lectures:

  • All lectures are hybrid and will be recorded.
  • Hybrid lectures take place in HS 13 Ernst Melan in the main building of the TU Wien.
  • Lectures will be only 60min. The remaining 30min minutes will be dedicated to solving practical questions in TUWEL. This can be done either directly in the lecture room afterwards, or later on.
  • Lecture 3 (Oct 18th) and 4 (Oct 25th) will be presented as a pre-recorded video in TUWEL, since Johanna Schmidt attends a conference on these days.

Important Dates

Submissions are done via TUWEL.

Every data science workflow consists of five stages: Discover, Wrangle, Profile, Model, and Report. The submission dates reflect these stages. The first submissions (Discover) on Nov 17th is mandatory to be enrolled to the lecture. A submission of this lab part will also mean that a certificate for this lecture will be issued. For submitting practical exams, the following deadlines apply:
