We have released version 4.4 of FlowChartX. It contains the following new features:

Simulated Annealing graph layout
The AnnealLayout class implements the Simulated Annealing graph layout algorithm. Simulated Annealing is a general-purpose optimization method used to solve large-scale combinatorial problems by simulating the process of heating and cooling of metal to achieve freedom from defects. Finding a nice arrangement of a graph is a combinatorial problem that can be reduced to assigning costs to graph configurations and finding the minimum cost configuration. AnnealLayout assigns costs to graph configurations by evaluating different aesthetic criteria such as distance between nodes, length of links and the number of link crossings. Thus the best configuration found will have good aesthetic properties.

Miscellaneous
~ Limit the number of links bends in LayeredLayout by setting StraightenLongLinks.
~ Color of the tracking rectangle in the Overview control can be set via the TrackingRectColor and TrackingRectColorAlpha properties.
~ More precise text measuring in GDI+ mode.
