Problems solved by technology

[0002] Most of the current knowledge graphs in the industry are based on the digital visualization tool D3, but the existing D3 has limited display of large amounts of data. The limit display is about 5,000 knowledge graph nodes, and D3 has a low utilization rate of the computer's CPU and GPU. The fluency of interactive operations under volume display is very low, and it is easy to cause the page to get stuck

Abstract

The invention relates to a D3-based knowledge graph data node rendering method and system. The D3-based knowledge graph data node rendering method comprises the steps of constructing a static projectand introducing a digital visualization tool D3 into the static project; converting the 2D coordinates of the knowledge graph data nodes from a JSON format into a binary system; converting the binary2D coordinates obtained by conversion into 3D coordinates; in the static engineering, using D3 to draw WebGL elements based on the 3D coordinates in a Canvas, and completing rendering of knowledge graph data nodes. The D3-based knowledge graph data node rendering method has the beneficial effects that 1, the data volume of display data nodes of the knowledge graph is increased; 2, the utilizationrate of D3 to a CPU and a GPU is improved; and 3, the interaction fluency of the knowledge graph under a large data volume is improved.

Description

technical field [0001] The invention relates to the field of web development of information technology, in particular to a D3-based rendering method and system for knowledge map data nodes. Background technique [0002] Most of the current knowledge graphs in the industry are based on the digital visualization tool D3, but the existing D3 has limited display of large amounts of data. The limit display is about 5,000 knowledge graph nodes, and D3 has a low utilization rate of the computer's CPU and GPU. The fluency of interactive operations under volume display is very low, and it is easy to cause the page to get stuck. Contents of the invention [0003] In view of the above technical problems, the present invention provides a D3-based knowledge graph data node rendering method and system. [0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a D3-based knowledge map data node rendering method, comprising: ...
