The 4 categories give a rough time as to when a task should be done,
and reflect an assessment of the task's ease multiplied by its importance.
Thus, orthogonal layouts are extremely important but not easy,
so they fall into category 2. The following denote owners:
AB=Arif Bilgin
DFWC=Don Caldwell
DP=Dwight Perry
ERG=Emden Gansner
JCE=John Ellson
SCN=Stephen North
YH=Yifan Hu
ALL - Revise the buglist; fix bugs SCN - Update dot/neatoguide
JCE - Extend attribute set for line styles JCE - Allow arrowheads in the middle of edges JCE - Support single, uniform font descriptors à ala pango ? - Move generic node adjustment and spline routing out of neato AB - smyrna 1 QT 2 Widget library. Plugins. Printing. 3 Full dotty replacement incl. history, checkpoints, scripting, undo. 4 General editor YH/ERG - Clusters in sfdp YH/ERG - Fixed nodes in sfdp ERG - Finish orthogonal edges (edge labels in dot; ports) ERG - Add stack frames/local variables to gvpr ERG - GvMap integrated tool ? - Finish handling of loops using arbitrary ports
SCN/AB - New dot core:
- new mincross + clusters (partial prototype)
- symmetrize layouts
- Ulrik's improvements with network simplex
JCE - Shapes
- SVG grammar or other grammar to specify node and arrow shapes
- user-defined nodes in all code generators
YH/ERG - additional graph packing strategies
? - Filters for Chaco formats.
? - Library for bundled edges (Given two sets of nodes, with positions,
forming a bipartite graph, return splines to bundle the edges together)
? - better spacing of edges along the side of a node, especially
exposed port sides. Perhaps extend compass points to S, N, E, W to
mean anywhere along that side.
ERG - Tabular layout in rows and columns in dot (swim lanes)
Crossing minimization with some nodes in columns
? - Enable arbitrary depth clusters in neato using IPSEP
? - Allow mixed edge types within the same graph
? - Off-load more to pango, such as linebreaks, right-to-left characters, etc.
? - Allow text at an angle
Generic label placement modifying graph layout. Support for compound graphs. Allow varied layouts within clusters - recursion Spline router improvement (Gordon's improvements, alpha adjustments, fewer inflection points) Fast incremental hierarchical layout Edge routing with just two vnodes per edge (after Kaufmann) Graph language improvements local name spaces subclassing Shapes - new parallelogram shape where angle is fixed for varying text True orthogonal layouts. Support rank=min/max within the context of a cluster
Dot with aspect ratio allowing clusters Dot with aspect ratio < 1 Incremental layouts Dot with orthogonal, coalesced edges (e.g., this) Generalizing the above, support for hyperedges Constraint-based layouts Display of large-graphs (hair ball problem) - relaxing constraining edges - edge bundles - other Venn diagrams Integration of geographic info - maps Aspect ratio in dot with clusters Dot with fixed width Adjust graph to allow no edge-node overlap with line segment edges
SCN/ERG - Move dot to cgraph SCN/ERG - new rank assignment JCE - Extend attribute set for line thickness ERG - New text labels with font elements <FONT> ERG - Allow edges as line segments and polylines ERG - New multiedge code YH/ERG - New overlap adjustment strategies YH - Faster fdp (sfdp) ERG - Variable port depending on layout ERG - Better aspect ratio in dot ERG - New orthogonal routing code JCE - use floats not ints where appropriate YH - Filters for Matrix Market ERG - New text labels with font elements <B>, <I>, <TT>, etc. (support via fontconfig or egregious hacks) AB - smyrna 1 Design incl. 3D navigation, multiple graphs and viewports. Avoid modes. 2 Stable GUI. 3D mouse. DFWC - Lightweight edge labels in dot DFWC - Lightweight node labels in dot, just placed outside nodes. DFWC - Generic label placement without modifying graph layout. YH/ERG - Treemaps DP/ERG - Clusters/HTML tables with rounded edges ERG - Filters for GraphML
JCE - Revise GV_FILE_PATH to work as directory list; remove loose ends ERG - eliminate the nonlinear adjustment - use convex hull or alpha shapes
