Visualization Design and Implementation of Post-earthquake Emergency Information Based on DataV

This article addresses the problems of lack of dynamics in post-earthquake emergency information display and insufficient element performance. Based on the Card model and DataV as a visualization tool, three steps are taken from the emergency data acquisition period according to the three steps of information collection, information integration and information display design to carry out the visualization interface example design, and the ideas and methods for the future development of information visualization are discussed.
