Abstract

The invention discloses a graph layout method and device. The method includes the steps that a control node is preset, the maximum hop between other nodes and the control mode is determined according to an adjacency relationship list, and adjacency relationships between the nodes are saved in the adjacency relationship list; multiple node rings are sequentially determined with the control mode as the circle center, wherein the number of the node rings is consistent with the maximum hop, and each node ring corresponds to one hop; the nodes are sequentially distributed at corresponding positions of the node rings corresponding to the hops of the nodes; every two nodes with the adjacency relationship are sequentially connected according to the adjacency relationship list. By means of the method, node layout can accord with an energy model as much as possible, energy of a system can be primarily reduced, and accordingly optimization efficiency of a force-directed algorithm can be improved.

Description

technical field [0001] The invention relates to the technical field of information technology visualization, in particular to a method and device for graph layout. Background technique [0002] A graph is an abstract data structure that is often used to model information structures. Graph can model arbitrary information of objects in the real world and represent the relationship between objects. In recent years, the research on information technology visualization has become more and more extensive, and information technology visualization has also been widely used in various fields. Graph layout is an important technique to use graph structure to solve information visualization problems in the real world. [0003] Drawing technology is an interdisciplinary field of information visualization and applied mathematics, which mainly studies the mapping relationship from graph to geometric space. The content of drawing technology is extremely rich, mainly to meet the basic req...
