In this thesis we present a model for transitions between different 2D scatter plots of the same underlying multivariate data. We examine three types of transitions: linear interpolation, rotation, and spline paths. These are implemented in a TypeScript library for web-based applications. In the library, we also provide user interface components, and utilize them for an example application for interactive use of our model. To evaluate the different transitions, we conducted an online user study with 25 participants. We compared the effectiveness of each method for tracing points or clusters through the animation. Using a questionnaire, we also surveyed the perceived difficulty of the tasks, as well as the appeal of each method. In the study, we found most transitions perform similarly. When tracing points through an animation, users generally preferred flatter transitions similar to linear interpolation and achieved worse performance especially in a 3-stage 3D rotation transition. We also found two view changes to be the longest transition for comfortably tracking points. When tracing clusters through an animation, all transitions were similar, though in questionnaires the same three-stage rotation performed worse again.
