New features (November 2012)
We have provided Graphviz with some additional graphics, which can be used to provide more semantic information in a graph or enhance its aesthetics. These include gradient fill for nodes and graphs; striped and wedged fills, so the amount of each color can be used to represent some percentage; new node shapes pertinent to the synthetic biology community (Thanks to Jenny Cheng); and curved edge routing.
New features (September 2011)
We added lightweight edge labels (xlabel) and tapered edges (as a style). There was a recent paper by Holten et al about a study of the readability of various edge styles. We're working on some examples and documentation. Here are some examples. (We need a better example for xlabels, because they can float, and aren't stuck to the upper left of the node.)
New Release 2.28 (Summer 2011)
The 2.28 release of Graphviz incorporates GvMap (formerly GMap, or "graphs as maps"), an invention by Emden Gansner, Yifan Hu, and Stephen Kobourov. Try the cool interactive demos showing maps of music, TV, books, and more.
For people (like us) that care about such matters, we worked pretty hard to tweak the font rendering code, to
John Ellson finished porting Graphviz to Solaris OpenCSW.
We changed our license to the EPL (Eclipse Public License). (A wikipedia article attempts to explain the differences, which we believe to be fairly limited but the change may help some commercial licensees.)

Graph Drawing 2010
|``Sketch a rough shape with your finger and Instaviz transforms what you drew in a split second. Sketch a link between two shapes and Instaviz quickly redraws the graph with the best layout. No pesky user interface getting in the way of your brainstorm!'' (Well, maybe.) Read more.|
Graph Visualization Is Our Brand
Dioramas featuring network visualization from our lab were displayed at Washington Dulles airport (click on the airport photo to see locations). Mercury Seattle designed the ads with layouts made by Bill Cheswick. Bill combined tools he wrote at Lumeta and sfdp, a new scalable visualization program by Yifan Hu that is slated for the next main release of Graphviz. Meanwhile, here's a pdf for your enjoyment (3.1M).

Graphviz for Windows (2007)The 2.16 release occurred on 9 November. In general, in addition to various bug fixes, the release provides three new node shapes, "tab", "box3d" and "component", provided by Diomidis Spinellis, and we've added support for the "image" and "imagescale" attributes to simplify the use of images in nodes.
More importantly for Windows users, the release provides many system features which were previously only available on Unix systems. These include:
- Rendering using the Cairo library. In particular, using this it is possible to get PostScript output using general Unicode input and non-Type 1 fonts.
- Font naming using the fontconfig library.
- Support for plug-ins. With this architectural change, users can add their own layout engines or renderers without having to make any changes to the Graphviz programs.
gvprtool, which enables a user to process graphs simply.
Tools built on GraphvizYou can find great tools and demos in our Resources section. Here's a sample:
John Currier's SchemaSpy is runner up as O'Reilly's most useful Java-Oracle tool.
According to the reviewer, Paul Brown, the winner is Oracle's own Project Raptor, so this award is quite an accomplishment for a one-person, open source project. SchemaSpy relies on Graphviz for visualization. Its description on SourceForge explains:
SchemaSpy analyzes schema metadata, letting you click through the hierarchy of your tables' parent/child relationships either graphically or through HTML tables. It works with just about any RDBMS given an appropriate JDBC driver. SchemaSpy also identifies several common schema anomalies.
New scalable algorithm for directed graphs (Oct. 2005)Graphviz now incorporates DiG-COLA (directed graph constrained layout) algorithm for which Yehuda Koren and Tim Dwyer (Monash University) won the IEEE Infovis 2005 Best Paper Award. (Try: neato -Gmode=hier). Neato already incorporates the stress majorization algorithm presented at Graph Drawing 2004, that supports an alternative model for graphs with nodes of high degree. (Try: neato -Gmodel=subset)
New plug-in architecture for layout, scripting languages and renderers (Oct. 2005)Graphviz now has a more modular architecture that supports multiple layout engines, scripting languages, and renderers. About a dozen scripting languages, including perl, python, tcl and ruby are supported. An optional backend with high-quality antialiased graphics is written in cairo, and it also provides portable interactive graph canvas objects in GTK+. This work was done by John Ellson.

Pixelglow's outstanding adaption of Graphviz 1.12 won two 2004 Apple Design Awards: Best Mac OS X Open Source Product and runner up, Best Product New to Mac OS X. The awards were presented at the 2004 Apple World Wide Developers Conference at the Moscone Center in San Francisco on June 29. Congratulations to Glen Low and the Graphviz core team. (Also, see inside the trophy!)
R-Graphviz (Aug. 2004)
R-Graphviz is a graph layout and display module from the Bio-Conductor project for the R statistics language. Thanks to Robert Gentleman and Jeff Gentry (Dana Farber Cancer Institute, Harvard) for leading this work. (In Sept. 2004, an article on applying R-Graphviz to displaying metabolic pathways was published in the R newsletter.)
HTML-like labels (Feb. 2004)This new label formatter supports many helpful options for text formatting, coloring and URL linking, similar to HTML tables. (Special thanks to Emden Gansner and Serban Jora.)
Circo - circular layout tool (Feb. 2004)
Mac OSX port (Feb. 2004)A quite elegant-looking port of graphviz to Mac OSX includes a new document-based GUI, export to PDF and many bitmap formats, full alpha transparency, native font support and anti-aliasing. (Special thanks to Glen Low.)
gvpr (aka gpr)The generic graph processor (written by Emden Gansner) has some new features. It has string and substring matching and substitution using POSIX shell pattern syntax. It also has a lock primitive to save graphs in the input stream, making it easier to write scripts that operate on multiple graphs. It now provides access to common math functions and a random number generator. There are additional graph traversals available.
gvpackThe tool packs multiple layouts using a 2D tiling algorithm based on polyominos. It's a standalone tool using the same algorithm that is shown below for neato -Gpack.

WinGraphviz updateAdded CMAP support. The download includes support for the most common output formats for dot and neato, and sample ASP code. Thanks to ood Tsen!
Neato -GpackThis feature (due to Emden Gansner) places connected components by a new tiling algorithm that improves both compaction and running time.

DynagraphBeta code is included in the source release, but it is not compiled by default. Also see the mpeg and Quicktime demo movies.
Graphviz 1.8.+See the download page for packages including perl and Python APIs.
We've incorporated a new collection of graph tools including "gpr", a graph stream editor, in the spirit of awk. (Thanks to Emden Gansner for these tools.) webdot.cgi server (in perl). See instructions at top of the script regarding use.
The SVG driver is more usable.
All known memory leaks banished! Rock solid.
