Data processing method and device for setting up tree diagram

Abstract

The invention relates to a data processing method and device for setting up a tree diagram. The method comprises the steps: determining a first child node corresponding to a first father node in a to-be-processed data tree; obtaining the number of nodes of the first child node; when the number of the nodes is greater than a preset upper limit threshold value, determining arrangement information for arranging the first child nodes in at least two rows according to the upper limit threshold value and the number of the nodes; and generating a tree diagram corresponding to the to-be-processed datatree according to the arrangement information. According to the technical scheme provided by the embodiment of the invention, the sub-nodes can be dynamically adjusted into a plurality of rows and aplurality of columns according to the number of the sub-nodes, so that the layout of the tree diagram cannot be supported to be very high or very wide, and the content of the tree layout is easier tocheck; meanwhile, according to the method, the tree diagram can be reasonably arranged without back-end support, so that the tree diagram is convenient to check, and therefore, data transmission witha back end due to the fact that related data of the tree diagram needs to be cached can be avoided.

Description

technical field [0001] The present application relates to the technical field of computer software, in particular to a data processing method and device for building a tree diagram. Background technique [0002] Graph visualization (Graph Visualization) is the theory, method and technology of constructing, drawing and displaying a subgraph of a graph database using visualization technology. The number of drawn nodes and edges can reach tens of thousands to hundreds of thousands. Users sometimes need to visualize graph data as a tree structure. The main methods are as follows: [0003] (1) Based on the front-end framework (such as D3.js, ECharts, etc.) [0004] Take advantage of the framework's tree layout plugin. [0005] (2) After the calculation is completed by the back-end technology, it returns to the front-end (such as Java, Scala, etc.) [0006] The backend caches the query results and incremental expansion results of the graph, and uses the backend technology to ar...

Problems solved by technology

[0010] 1) The complexity of the backend increases, and the backend needs to cache the results of each query and extended query, so that the backend has a complete graph;

[0011] 2) The amount of data transmission increases, whether it is query or extended query, all data needs to be sent to the front end

[0012] Aiming at many technical problems existing in related technologies, effective solutions have not yet been provided
