VO & visualisation: ARGOS: advanced visual analytics for simulations

Description
VO: The Virtual Observatory (VO) is a set of APIs to find, access, and use astronomical data. If you have ever used TOPCAT or Aladin, you probably have used the VO, too. But since it is APIs, a natural place to deal with them is a library, and pyVO is one such library for python. In this tutorial, we will explore data discovery and TAP queries from pyVO, going from catalogues to images.
ARGOS: modern cosmological simulations rely on sophisticated assumptions and generate rich, highly complex datasets. Troubleshooting their operation and interpreting their results remains challenging. Existing visualization tools offer powerful capabilities but often come with a relatively high barrier for entry, and are not designed with a focus on knowledge discovery through interactive and intuitive visual analytics.
We present ARGOS, an open-source, web-based environment for real-time visual analytics, tailored to cosmological simulation outputs and designed with an emphasis on user experience. ARGOS combines GPU-accelerated browser rendering for interactive exploration of large datasets with a template-driven approach that enables rapid adaptation to various types of data and analysis workflows.
