Product comparison is a common process consumers perform every day. However, current tools provide limited functions and poor visual designs. We present ManyLists, a product comparison tool that compares products’ features using Spatial Layouts with Animated Transitions. In addition colorcoding is used to highlight the best features among the products. A usability study with fourteen participants provided evidence that the visualization is easy to learn and the animated transitions are helpful. Finally we propose three guidelines for Spatial Layouts with Animated Transitions: break multi-step processes into small comprehensible steps, show animated transitions for each step, and use spatial layouts to indicate relationships among features.
