We have released version 5.6.3 of FlowChart.NET. It adds several customer-requested features and small improvements:

CompositeLayout algorithm
CompositeLayout partitions the diagram into several subgraphs and applies the algorithm specified via the SubgraphLayout property on each part. If the part is a tree, it is arranged using the algorithm specified via the SubtreeLayout property, which is set to a radial TreeLayout instance by default. Finally the algorithm specified via MasterLayout is applied on the graph that represents the overall partition. By running the polynomial-complexity layout algorithms on small subgraphs, CompositeLayout is able to process a large graph much faster than if a layout algorithm is applied on the whole graph.

Miscellaneous
~ If there is only one used execution path after a branching and up to two empty ones, FlowchartLayout will now center the used path under the branching start node.
~ OrthogonalLayout now produces more compact layouts with less link bends if MinimizeLinkBends is enabled.
~ The DisableMirroring constraint prevents users from flipping a node by dragging a handle over the opposite node side.
~ A new sample project called "Scripting" shows how to associate scripts with flowchart nodes to design and run actual algorithms represented by the flowcharts.
