Abstract: Visualization is key for understanding intricate systems and complex machine learning pipelines. We at CNets and IUNI have been developing Helios-Web, a groundbreaking web-based visualization platform tailored for large networks and embeddings. Helios-Web enables real-time visualization of million-node networks, offering users valuable insights and easy interpretation of results. Accessible through your web browser, this versatile tool has a wide range of applications. We will demonstrate the of the tool through three compelling applications. The first application showcases its potential in the Science of Science field, where publications, authors, and scholarly data will be presented in interactive 2D and 3D maps. The second application highlights its integration with the OSoMe platform, visualizing Twitter networks based on queries such as hashtags and offering real-time insights into bot influence. Lastly, we exemplify Helios-Web’s utility in exploring neural network embeddings and how it was instrumental in developing and understanding our robustness modularity approach.
