  The computational notebook serves as a versatile tool for data analysis.
However, its conventional user interface falls short of keeping pace with the
ever-growing data-related tasks, signaling the need for novel approaches. With
the rapid development of interaction techniques and computing environments,
there is a growing interest in integrating emerging technologies in data-driven
workflows. Virtual reality, in particular, has demonstrated its potential in
interactive data visualizations. In this work, we aimed to experiment with
adapting computational notebooks into VR and verify the potential benefits VR
can bring. We focus on the navigation and comparison aspects as they are
primitive components in analysts' workflow. To further improve comparison, we
have designed and implemented a Branching&Merging functionality. We tested
computational notebooks on the desktop and in VR, both with and without the
added Branching&Merging capability. We found VR significantly facilitated
navigation compared to desktop, and the ability to create branches enhanced
comparison.
