FlowChart.NET 5.3 adds support for SVG rendering. If anyone is interested in this, please try the beta version:

https://mindfusion.eu/_beta/fcnet53.zip

SVG drawings can be displayed using the SvgNode class, as shown below.

SvgContent svg = new SvgContent();
svg.Parse(@"scorpion.svg");

SvgNode node = new SvgNode(diagram);
node.Content = svg;
node.Bounds = new RectangleF(10, 10, 100, 100);
diagram.Nodes.Add(node);
 

This requires a reference to the mindfusion.svg.dll assembly.

SvgNode is derived from ShapeNode and has all of its properties and methods. SVG could also be rendered without creating a node, by calling SvgContent.Draw(IGraphics, RectangleF) in response to custom-draw events such as Diagram.DrawBackground.

We have uploaded a new build of v5.3 that allows creating and modifying items in DiagramView3D:
https://mindfusion.eu/_beta/fcnet53.zip

To enable this, set the DiagramView3D.Behavior property to a value different than DoNothing. The DoNothing behavior implements the functionality from previous versions where the only possible interaction was moving the camera around the 3D scene. Now it is possible to draw new items, select and modify them. At this time drawing new links is done by holding Ctrl while drawing with the mouse. Version 5.3 allows only a single item to be selected in DiagramView3D; we'll implement multiple selection in next releases if there are requests for this.

This v5.3 beta build adds the FlowchartLayout class, which can be used to arrange flowcharts representing source code:
https://mindfusion.eu/_beta/fcnet53.zip

The algorithm recognizes program code -like patterns in the graph, such as loops, sequences and if/switch branchings, and arranges them recursively as shown below. FlowchartLayout could be used to arrange other types of graphs as well, though with some restrictions. For example it treats all back links as loops in the code, and expects that they are nested - loop links starting closer to the stop node should end closer to the start node. Another similar restriction is that there shouldn't be any cross-links that connect different branches of a decision sub-graph.
