The present invention provides a community layout visualization method facing a large scale network, relating to the field of information visualization. On the basis of a force guiding layout, a hierarchical spatial decomposition model is introduced, and the computing time complexity of the repulsion force between nodes is reduced. A node degree controls the magnitude of node repulsion, thus the nodes with large degrees are far away from each other, and a community structure is clear. The community gravitation model is optimized, the computing time complexity of the community gravitation is reduced, and the method can be suitable for the community layout of a large scale network. For a node overlapping problem, the repulsion and gravitational force between overlapping nodes are adjusted, and the excessive gathering of the nodes is prevented. According to the method, the community structure information of a large scale network can be displayed, and the method is easy and simple to realize, and the layout speed is fast.
