FlowChartX version 4.9.3 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 Group class and bsContainer boxes), 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.



Arrow improvements
~ the component no longer keeps a separate segmentCount field, removing a common source of errors. The Segments property now calculates its value from ControlPoints elements.
~ the new bsSpline element of EArrowStyle enumeration draws links as interpolating splines that pass through all of their control points:
