From looking at this workflow, it becomes clear that the RO dataset becomes increasingly complex with every optimization iteration. In this work, we propose CIME4R, a novel visual analytics tool that aids scientists with analyzing RO data (i ). It helps scientists to make informed decisions during the RO campaign and review RO campaigns in retrospect, especially in the realm of AI-guided RO. CIME4R is open-source to allow the community to enhance the tool and share their input.
