Abstract: In this paper, the sector ring and spline visualization layout characteristic of hierarchical edge bundles are analyzed in detail, and design details of using spline curves to render bundles to reduce the visual complexity are expounded. On the basis of comparative analysis of the characteristics of D3 visualization library based on SVG, the paper mainly analyzes the process to render spline curves by using Bezier curve segments, and implements hierarchical edge bundles with highlight, rotation and more interactions using D3. The results of visualization experiments using code duplication detection data prove the technical feasibility of eierarchical edge bundles based on D3, and show the feasibility of hierarchical edge bundles in software visualization analysis.
