[0004] In the big data environment, this kind of data visualization service can be easily generated in real time, but the current mainstream elastic layout algorithm in the network layout algorithm has defects in display. The generated images are often nodes gathered in the center of the screen, making it difficult to distinguish the relationship Information, when the amount of node data is greater than 10,000, the calculation of node coordinates can be as many as hundreds of millions of times, and the calculation takes a long time and consumes a lot of computer memory

Embodiment 1
[0039] Please refer to the attached figure 1 , which is a schematic flow chart of a network diagram visual layout method provided in Embodiment 1 of the present invention, the method is applicable to the scene of network diagram visual layout, and the method is executed by a network diagram visual layout device, which can be implemented by software and / or Hardware implementation, integrated inside the operating terminal equipment. The method specifically includes the following steps:
[0040] S110. Obtain area information of the network graph, node data in the network graph, and association information between the node data.
[0041] It should be noted that the area information of the network map includes area width information and height information, for example, the screen area information where the network map is located may be 10 cm in width and 5 cm in height. There are 10 node data in the network diagram, respectively A, B, C, D, E, F, G, H, I, J, and the associated in...

Abstract
The invention discloses a method and a device for visual layout of a network diagram. The method comprises the following steps of obtaining regional information of the network diagram, node data in the network diagram and associated information between the node data; determining hierarchies where a center node and each node are located according to the associated information and uniformly distributing the nodes at the same hierarchy in a region of the last corresponding hierarchy; and determining coordinates of the center node and the coordinates of the nodes at the different hierarchies according to the regional information of the network diagram. According to the method and the device, through carrying out hierarchical layout on the associated information between the node data in the network diagram, a problem that the node layout is centralized at the center of a screen is solved, the hierarchical relationship is clear, an operation algorithm is optimized, and the cycle index and the memory consumption of a computer are reduced.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of graph visualization, and in particular, to a method and device for visual layout of network graphs. Background technique [0002] In the era of big data, there are many different types of data, such as: user data, UGC (User Generated Content, user-generated content) on social media platforms, geographic information of mobile terminals, development of Internet of Things technology, etc., and the number is increasing rapidly. According to the era of big data, the emphasis is on comprehensive processing capabilities for large-scale data, and its characteristics can be summarized into four "Vs", namely: variety (Variety), volume (Volume), velocity (Velocity) and value (Value). ; means diverse data sources, huge data volume, fast and low-cost processing. In order to achieve the best display effect, we need to adopt a special way to display data, to explain, analyze and apply it, and to a...
