Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0036] The present invention provides a method for expanding the layout of the map, which obtains the boundary of the existing map and forms an ordered coordinate set of the boundary,

[0037] According to the distance between the extended node and the node coordinates in the ordered coordinate set, the nodes are arranged in a positive order to obtain the sorting result,

[0038] For the newly added nodes that are not in the existing map and associated with the extended node, calculate the covering circle and the original position of the covering circle, and obtain the moving route of the covering circle in the existing map according to the sorting result,

[0039] The layout posi...

Abstract

The invention discloses a map extension layout method, and relates to the field of data visualization analysis. The method comprises the following steps: acquiring an existing map boundary, forming an ordered coordinate set of the boundary, performing node positive sequence arrangement according to the distance between an extension node and a node coordinate in the ordered coordinate set to obtain an ordering result, calculating a coverage circle and an original position of the coverage circle for a newly-added node which is not in an existing map and is associated with the extension node, obtaining a moving route of the coverage circle in the existing map according to the sorting result, determining a layout positioning circle by moving the coverage circle according to the moving route, and adjusting the layout positioning circle to complete layout extension of the map.

Description

technical field [0001] The invention discloses a method, which relates to the field of data visualization analysis, in particular to a method for expanding the layout of graphs. Background technique [0002] With the continuous development of computer technology and the continuous improvement of informatization, society has entered the era of interconnection and intelligence, and a large amount of data has been generated. The knowledge map is a tool for descriptive analysis of these data. Knowledge graphs are used to describe various entities and overviews and the relationships between them, and can be applied to chatbots, search intent recognition, knowledge storage, and other fields. Graph is the means of displaying knowledge graph. [0003] Expanding nodes is the basic function of the map. The core of the map display effect is the layout. A good layout can make the map clearer and easier to find key points. However, the current existing layouts are all separate and do ...
