The visualization of hierarchically structured data over time is an ongoingchallenge and several approaches exist trying to solve it. Techniques such asanimated or juxtaposed tree visualizations are not capable of providing a goodoverview of the time series and lack expressiveness in conveying changes overtime. Nested streamgraphs provide a better understanding of the data evolution,but lack the clear outline of hierarchical structures at a given timestep.Furthermore, these approaches are often limited to static hierarchies orexclude complex hierarchical changes in the data, limiting their use cases. Wepropose a novel visual metaphor capable of providing a static overview of allhierarchical changes over time, as well as clearly outlining the hierarchicalstructure at each individual time step. Our method allows for smoothtransitions between tree maps and nested streamgraphs, enabling the explorationof the trade-off between dynamic behavior and hierarchical structure. As ourtechnique handles topological changes of all types, it is suitable for a widerange of applications. We demonstrate the utility of our method on several usecases, evaluate it with a user study, and provide its full source code.
