ParaView tutorial
Time: 3 hours
Time: 3 hours
Thomas Theußl
Abstract:
In this tutorial, tailored towards beginners with little to no previous experience,
we will
introduce ParaView, a highly-scalable,
open-source,
multi-platform data analysis and visualization application built on top of VTK,
the Visualization Toolkit. ParaView users can quickly create visualizations to
analyze their data using qualitative and quantitative techniques. The data
exploration can be
done interactively in 3D. Attendees will participate in a hands-on session working
with ParaView
to create 3D visualizations of scientific datasets.
Thomas Theußl
is with Consivi KG in Deutschlandsberg, Austria, which he founded in 2025, offering
consulting,
support, and development in scientific visualization. His research interests include
visualization techniques, mathematical foundations of visualization, and
applications of
visualization. Theußl received his Master's degree in Computer Science from TU Wien
in Austria.
He has published tutorials on ParaView and Avizo on YouTube. Contact him at thomas.theussl@consivi.com.
Orange for Biomedical Data Analysis: From Visual Analytics Workflows to
Interactive Communication
Time: 3 hours
Time: 3 hours

Abstract:
This hands-on workshop introduces Orange Data
Mining
as a visual programming environment for biomedical data analysis, starting with the basics
of visual programming and workflow design and progressing to practical biomedical data
analysis workflows. Participants will learn how to build interactive Orange workflows,
explore data visually, and apply them to case studies in single-cell gene expression
analysis and survival analysis. The workshop will conclude with Orange Lab, a web-based
version of Orange that also features component exposition, allowing selected workflow
elements to be embedded in interactive web pages while remaining connected to the underlying
analysis pipeline. The workshop will finish with an under-the-hood look at the Orange Lab
through a live vibe-coding session to demonstrate the creation of new visual analytics
components. The tutorial is tailored for beginners – no prior experience with Orange or the
Orange Lab frameworks is required.
