Before revision:  Moreover, we introduce a new method to measure the stability of time-dependent treemaps which explicitly incorporates the change in the input data. We analyze and visually summarize the results with respect to both visual quality and stability  .
After revision:  We experimentally test the validity of this classification on more than 2000 datasets, and analyze the relative performance of 14 state-of-the-art rectangular treemapping algorithms across varying features. Finally, we visually summarize our results with respect to both visual quality and stability .
