For the latest stable version:

New Features in JS Diagram 3.2.1

  • Export to SVG
    • The SvgExporter class creates a Scalable Vector Graphics (SVG) drawing from the content of a Diagram. The exportElement method returns a DOM element that can be directly added to the page. The exportString method returns an SVG string that can be saved in local storage or submitted to server.
function onExportSvg()
    var diagram = $find("diagram");
    var exporter = new MindFusion.Diagramming.SvgExporter();
    var svgElement = exporter.exportElement(diagram);
    document.body.appendChild(svgElement); = 'fixed'; = 100;

  • AMD module
    • The diagramming.js script can be loaded as an AMD module now. If it detects an AMD loader during startup, it will list common.js as its dependency, so it is enough to require only diagramming.js as application's direct dependency:
MindFusionImpl = "StandAlone";

        // create a Diagram component that wraps the "diagram" canvas
        var Diagram = MindFusion.Diagramming.Diagram;
        var element = document.getElementById("diagram");
        var diagram = Diagram.create(element);
        var node = diagram.factory.createShapeNode(10, 10, 40, 30);
        node.setText("Hello, world!");
  • Miscellaneous
    • Arc definitions in custom shapes now follow correct SVG syntax (A rx ry x-axis-rotation large-arc-flag sweep-flag x y) instead of specifying bounding box and angles.
    • ShapeNode's Stroke attribute is now also applied to shape decoration elements.
    • Underlined fonts can be applied to the text of links.
    • RowCount and ColumnCount properties now exposed by TableNode.
