Abstract

The invention is applicable to the field of computer technology, and provides a data visualization method, apparatus, device and storage medium based on cactus tree. The method comprises: receive input data storing the related information of the preset leaf node, processing the relevant information, and obtaining a collection of all parent nodes and child nodes corresponding to the parent node inthe cactus tree, depending on the set of child nodes corresponding to each parent node, determining node radius and angle information of each node in the cactus tree, Based on the node radius and angle information of each node. The scalable vector graph of the cactus tree is generated and drawn, the interactive action of the user is detected, and the scalable vector graph is adjusted according tothe interactive action, so that the data visualization effect based on the tree structure is adjusted, and the spatial utilization rate and the spatial distribution effect of the data visualization are improved. The scalable vector graph of the cactus tree is generated and drawn, and the interactive action of the user is detected, and the scalable vector graph is adjusted according to the interactive action.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a cactus tree-based data visualization method, device, equipment and storage medium. Background technique [0002] In the research of hierarchical information visualization theory and technology, data information will be regarded as nodes in the tree, and the internal connections of data information will be abstracted as edges connecting nodes in the tree, finally forming a tree structure corresponding to the data information. And use visualization technology to display in the effective physical display area, so as to enhance the user's quick cognition ability of hierarchical structure data. After more than 20 years of in-depth research, tree diagrams have not only developed from a simple rectangular box to a practical visualization technique with good looks, but also become a common technique for encoding hierarchical data and supporting specific tasks.
