Nice to see Graphviz trending. I created http://agile.pics a couple years ago based on the .js graphviz library. The site is a thin wrapper that renders Graphviz of Sequence Diagrams from GitHub gists. Example: http://www.agile.pics/gist/163647fe40ae4911e469

agree completely; GraphViz is extraordinary.

for intance, Yifan hu (U Florida faculty, i think) maintains a spectacular gallery of very large graphs comprised of millions of nodes, all rendered using GraphViz (persisted and input to GraphViz as incidence matrices): http://yifanhu.net/GALLERY/GRAPHS/index2.html

The graphs in the gallery i liked to above were rendered using sfdp, one of the 5-6 layout engines in GraphViz, and which is the GraphViz engine of choice for very large undirected graphs not limited to a particular layout geometry

Phabricator had allowed for specifying dot notation in their markdown (remarkup) which would use graphviz to render the images in the comment. I loved this feature but it was removed due to potential exploits [0]. Is anyone familiar with how graphiviz-as-a-service could be possible while addressing these concerns? [0] https://hackerone.com/reports/88395 , https://secure.phabricator.com/T9408

As both a heavy phabricator user AND a graphviz lover, your comment got me quite excited....up until the part where it was removed :(

If you look through the task description on the phabricator task I linked, there is Paste file which has the contents of an extension to allow continued use of graphviz, however they state it's insecure and not supported.

The hairball problem sometimes has solutions. this is a filtering soltuion which works with all general layout methods: http://visone.info/wiki/index.php/Backbone_Layout

It also scales for large graphs

Earlier quoted context omitted.

I still think dot could be reimplemented in d3. I agree dot is very expressive but it's starting to feel like TeX where it works great until you need to mix it into more recent applications.

dagre.js uses DOT. https://github.com/cpettitt/dagre-d3

it uses the dot language, but not graphviz's dot layout engine
