The invention provides animation planning method and device of a dynamic diagram. The method comprises the steps of: responding changes of application nodes in the dynamic diagram, and dividing the changed node into atom partitions according to the relationship between the changed node and the current node; and clustering the atom partitions according to the clustering distance among the atom partitions to generate an operating list including clustering and/or atom partitions for planning the animation demonstration of the changes of the nodes in the dynamic diagram. The invention also provides an animation planning method of the dynamic diagram, which comprises the steps of: responding changes of application links in the dynamic diagram, and grouping the nodes in the dynamic diagram into different node groups according to the relevance of the nodes in the dynamic diagram and the key node, wherein the key node is directly connected with each changed link; and planning the animation demonstration of node motion caused by the changed link according to the node groups. The invention can plan the multi-stage animation demonstration of the changes of the dynamic diagram, and has better readability and animation demonstration speed.
