Information visualization is becoming an increasingly important tool for making inferences from large and complex data sets describing tokamak operational spaces. Landmark MDS, a computationally efficient information visualization tool, well suited to the properties of fusion data, along with a comprehensive probabilistic data representation framework, is shown to provide a structured visual map of plasma confinement regimes, plasma disruption regions and plasma trajectories. This is aimed at contributing to the understanding of underlying physics of various plasma phenomena, while providing an intuitive tool for plasma monitoring.
