Immersive analytics has become a significant research field with applications in natural sciences, in contexts that require users’ exploration and understanding of three-dimensional spatial data. Yet, working in three dimensions is particularly challenging due to crowded, occluded, or even undefined 3D structures. Thus, exploratory visualization in immersive environments has attracted researchers’ attention. Many questions remain to be explored and answered in this field, for instance, effective visualization techniques for large-scale and complex data, efficient interaction interface and techniques, collaboration structures of immersive visualization such as task sharing, collaboration patterns, awareness visualization cues and communication.
