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


The VU Visual Data Science will discuss how techniques from visualisation and visual analytics can be applied to data science. The lecture will start with a theoretical introduction to different concepts of visualisation and visual analytics (lecture 1 & 2). The second part of the lecture (lecture 3-5) will deal with the practical application of Visual Data Science, namely the selection of charts, and trust in visualisations. An overview of current applications and libraries will be given (lecture 6-8). The lecture part then concludes with the late-breaking research topics of trust in visual interpretation (lecture 9) and how AI methods are used in visualisation (lecture 10).

Lab Part

Lab organisation and submissions are done via TUWEL.

The lab part of the VU outlines the different stages of a data science workflow. Every data science workflow consists of five stages: Discover, Wrangle, Profile, Model & Report. We will work on all stages and see how visualization can be used in every stage (except Discover). The lab part has the following deadlines:

# Date & Time Description
D1 10.11.2021 23:59 Selection of topic & stage Discover finished - submission of short report (1 A4 page).
D2 17.12.2021 23:59 Stages Wrangle and Profile finished - submission of report (at least 3 A4 pages).
D3 18.01.2022 23:59 Stages Model and Report finished - submission of report (at least 3 A4 pages).
D4 19.01.2022 & 26.01.2021 Final presentations (with dashboard from Report stage).
