Viewing profile — graphviz

Once upon a time, people worked on making imaginary maps https://www2.cs.arizona.edu/~kobourov/PROJECTS/maps.html to visualize datasets like TV and music recommendations. It was fu…

"Fix all bugs"?

Is it easy to write a renderer in another program? Do people still say lazyweb?

Gratifying that it's still useful. A lot of improvements are possible, based on 20 years of progress in interactive systems, and just overall computing performance.

Absolutely.

Various tools use tool-specific graph attributes. For example, "rank" and "minlen" mean something to the hierarchical or layered graph layout tool (dot) but not to other layout too…

Don't most companies seek a supported product, like yWorks or Tom Sawyer Software in the case of graph layout? Isn't the EPL "weak copyleft", so LGPL-ish? Would companies raise sim…

One of the nice things about this work is that by assuming the environment is a web client, it supports some basic interactive exploration, and offloads a lot of bothersome renderi…

Interesting, glad to know it's been useful for some specific contributions. (Not questioning that interesting-looking, appealing displays as overviews for general awareness are als…

What do people learn from visualizations like this? What is the most important problem anyone has solved this way? Speaking as somewhat of a co-defendant.

And by "system" we mainly meant "transactional website."

Any ideas how these primitives could be used to implement an edge router for drawing natural-looking curves around obstacles in diagrams, as an improvement on the 25-year-old solve…

We learned the hard way, for some of us it's all too easy to make careless design errors that become baked-in and can't be fixed in a backward-compatible way (either at the DSL or …

haha yes

Random thoughts: Sketching backed by automated cleanup can be good for entering small diagrams. There used to be an iOS app based on graphviz: http://instaviz.com Constraint-based …

IIRC Tamara Munzner and some colleagues worked on visualizing large phylogenic trees. There's this, too, https://academic.oup.com/mbe/article/33/8/2163/2579233 and it's implemented…

Modularity is an excellent way of attacking complex problems. We can all play with algorithms that can carry on realistic conversations and create synthetic 3D movies, because peop…

Not ... even that interesting?

This seems like it could be done in a little script in the graphviz gvpr processor. Someone could implement this as a feature in graphviz. It might take a day to implement. There a…

It would be great to see new practical software for declarative specification of general 2D diagrams. With increasing emphasis recently on language-based tools, this is an excellen…

The Graphviz project often wished to find a convincing formal definition of what it means for curves (spline sequences) that connect two points and are routed around obstacles to b…

A lot could be said. If there's a mistake, it was the economy not providing sufficient resources to solve this problem well. There was certainly awareness of this topic and some at…

It's well understood, graphs can be conveniently represented as matrices/tables/relations, and they are equivalent to edge lists. It might be interesting to discuss to what extent …

Graphviz has its own foundation graph library, that's not used by any other project. It has its good and bad points. Based on that experience, we had our very own second-system-syn…
