However, for iOS users, Instaviz is a great little app. The programs mentioned above work fine on a computer, but I couldn't interact fully with them in iOS. (2) On an iPad interation with D3.js programs sometimes doesn't work well-at least in Safari. (1) Searching on various combinations of "D3" with "directed graph" and "edit" brings up a few more options. The graphs aren't directed, but this tool is better at layout. Kirsling's graph editor is part of his Modal Logic Playground.īen Guo's Force Directed Graph Editor, also in D3.js, is a similar tool. However, it's right there online, and it might be one all needs for some purposes. Kirsling's graph editor is not very smart about layout (although that might be fixable), is not designed to load data (although that's easy to add in D3.js), and it lacks other fancy features that some of the tools listed here include. (Learning D3.js's weird conceptual model is not necessarily a trivial project, even for experienced programmers). It doesn't include weighted edges, but it probably wouldn't be difficult to add that capability if you're willing to learn D3.js. Ross Kirsling's D3.js-based Directed Graph Editor is a simple and convenient point-and-click online graph editor. Src label = node $ īox label = node $ ĭiamond label = node $ Src, box, diamond :: String -> Dot NodeId I like the first approach more ("Haskell ids").Ĭf.

Considering dotgen vs graphviz closerīut looking into the examples, I see that dotgen can use "Haskell Of having existing libraries rather than rolling your own each time.īoth points are related. To pre-escape your Text/String values graphviz will do that for you Values and ensuring correctness under the hood (i.e. #DIRECTED GRAPH BUILDER HOW TO#Have spent a lot of time checking how to properly escape different Graphviz/Dot (such as dotgen, language-dot, or their ownĬobbled-together interface): be very careful about quoting, etc. I would like to stress to people considering using other bindings to That will almost look identical to actual Dot code. Make it such that you can define a graph using the monadic interface A Dot graph representation based loosely upon dotgen's monadic interface (with Andy's blessing) but with the various Attributes being.Within the next month, I should hopefully finally finish the new I assume his "plans" (about a monadic interface) have been implemented already: In a follow-up to the post mentioning dotgen, the author of graphviz gives some comparison between them (and other similar Haskell libs). diagrams-graphviz supposedly uses graphviz to layout the graph and diagrams to draw it."
