NEWS file for the gridGraphviz package

Changes in version 0.3

• Added support for "ellipse" node shape

• Removed 'phantom edges' from undirected graphs

• Added agopenSized() function to create Ragraph objects whose size is determined by graphviz

• agopenSized also passes edge weight information through properly, resulting in nicer looking graphs

• Added graphWidth and graphHeight functions to get graph dimension details easily for plotting

• Plot Ragraph objects at their specified size rather than fitting to the graphics device

• Added support for triangle, pentagon, hexagon, septagon, octagon, diamond and square node shapes

• Added support for edge labels

• Added support for dot/odot and box/obox arrow types

• Arrow length for "open" and "closed" arrows set to graphviz default, now handles arrowsize better

• Improved naming of grobs

• Named the graph viewports

Changes in version 0.2

• Handle node 'col' or 'fill' of ""

• Handle arrowsize more sensibly

• Support for arrowhead="dot"

• New argument 'nodesOnTop' for grid.graph() so that user can control whether nodes or edges are drawn last (on top).
