This tutorial provides a basic, beginner’s introduction to topological data analysis and visualization with the Topology ToolKit (TTK). While previous editions of the TTK tutorial [12, 13, 15, 17, 18] (2018 to 2022) were organized as mini-symposia (focused on the descriptions of TTK’s latest features), this year, in contrast, we would like to organize a very basic beginner’s hands-on tutorial. Specifically, the goal of this tutorial is to accompany attendees in the installation of TTK on their laptop as well as in the running of a few basic examples, all in a very beginner-friendly step-by-step description. This decision is motivated by attendee feedback which we collected at previous editions of the TTK tutorial. We address this feedback in this tutorial proposal. Then, for the first time, beginners would be able to come to the tutorial without prior TTK experience, and walk out with TTK installed on their system, capable of running a few examples and ready to go further. We believe this basic hands-on tutorial will facilitate the adoption of TTK and topological techniques to a broader audience. The tutorial will be organized as follows. The first hands-on exercise will be dedicated to the installation of TTK. The second hands-on exercise will be focused on ParaView’s basic usage. The following three hands-on exercises will be dedicated to the step-by-step replication of three examples extracted from TTK’s online example database [57] (vortex extraction in fluid dynamics, Morse-Smale complex extraction in quantum chemistry and merge tree comparison in ensemble data).
