NetDiagram version 5.3 contains the following new features:

SVG nodes in Canvas mode
The SvgNode class represents nodes that can display SVG drawings. SVG graphics are rendered instead of Image, and on top of the geometry rendered by the base ShapeNode class. The SVG drawing of the node is specified through its SvgUrl property.

Import diagrams from SVG
The SvgImporter class allows importing Scalable Vector Graphics files (*.svg) into MindFusion.Diagramming. Each top-level SVG group element is imported as a separate SvgNode, whose Content is set to the group's child elements. If the SVG file was exported from Visio or OpenOffice Draw, SvgImporter will create DiagramLink objects for groups it recognizes as connectors in order to recreate the original diagram model, though in this case it will not preserve fully the original appearance of connectors in SVG.
