We have released version 1.1 of DiagramRT. It contains the following new features:

Tree map layout
Tree maps represent hierarchies by nesting child nodes within their parents, where the areas of leaf nodes are proportional to their Weight values. Unlike other layout algorithms, TreeMapLayout expects hierarchies to be defined via grouping or containment (see AttachTo method and ContainerNode class), and will ignore any links in the diagram. The diagram area covered by the topmost nodes in a hierarchy is specified via the LayoutArea property. By default, the layout tries to keep the ratio of node sides as close as possible to one. However this could make it hard to distinguish separate levels of the hierarchy. To alleviate that, set Squarify to false, and child nodes will be arranged either as a row or a column inside their parent node, alternating directions for each level. The drawback is that when Weight ratios differ greatly or nodes contain many children, some nodes could end up with very narrow rectangles.



Decision flowchart layout
DecisionLayout arranges simple flowcharts consisting of decision boxes with up to three outgoing links per node and activity boxes with a single outgoing link per node. The nodes are arranged in columns and rows, whose distance depends on the HorizontalPadding and VerticalPadding property values. When links share the same row or column, they are placed at a distance specified via LinkPadding. The layout arranges nodes recursively starting from StartNode. If StartNode is not specified, the algorithm selects the root of the deepest branch of the graph's spanning tree as start node.



Miscellaneous
~ Layout algorithms now automatically resize diagram's Bounds if it's not large enough to fit the arranged content. To revert to old behavior and keep fixed Bounds size, set GrowToFit to false.
~ LinkLabels are now copied by DiagramLink copy constructor and clipboard methods.
~ ContainerNode now displays a caption bar when its Shape is set to Rectangle or RoundRect. The caption bar height is controlled via the CaptionHeight property.
