Abstract
The invention discloses a method for displaying a weighted tree based on hyperbolic geometry, comprising: obtaining weighted tree data defining a weighted tree structure; positioning the root node in a negatively curved space as a center, based on the weighted tree defining data; based on the weighted tree defining data, performing layout processing for each parent node and all its direct child nodes from top to bottom recursively, until all the nodes in the tree have been laid out in the negatively curved space, wherein the higher the weight of an edge connecting the parent node and each of its direct child nodes is, the shorter the distance between the parent node and the child node is; mapping the layout data from the negative curved space to an Euclidean plane; and displaying the mapped data in display.
