JDElite Diagram Builder is a Web flowchart editor for creating complex graph diagrams, based on JavaScript, HTML 5 and node.js. Its on-screen help and outstanding editing capabilities allow you to create quickly and easily flowcharts of any size. JDElite Diagram Builder’s unique feature is that it offers unmatched readability to the most complex diagrams. This is achieved by the proprietary algorithms for orthogonal edge routing of directed graph diagrams with highly efficient edge crossings reduction (patent No. US 10,424,096).
