Whenever I see a new graph visualization tool, I instantly start dragging the nodes around like a madman to see how well the graph "balances" in the viewport. I soon noticed there was a tutorial was running while I was manipulating the position of the nodes, and regardless of how much stretching and pulling I did to try breaking the tutorial, it worked flawlessly as if I wasn't even touching it. That, I thought, was really awesome. Well done!
This actually is the power of the algorithm behind webcola, not totally anything greuler does. Still cool though :)
Looks nice. I do find the headlines drawing themselves a letter at a time to be kind of distracting. I makes it hard to scan down the page, as the headlines aren't there.
It is like the web version of the typewriter animation in powerpoint.
Agreed. The font choice was also very odd. Everything else looks incredibly cool though!
hehe yep I should've chosen a better font
Very cool! I was lazily working on something similar for a project, and might be able to drop this in and save a ton of time.
If the author reads this, might I suggest some examples using the label attributes of nodes and edges? It'd be great to see a graph annotated (potentially with some image or link tags embedded for further browsing?).

thanks! right now I'm working on more examples where the information on the edges is used like finding the minimum spanning tree or the shortest path from a source vertex, I'd suggest to open a new ticket in the repo issues section so I can take a look at it later, thanks for the feedback
How many nodes/edges can be handled by this ? I'm working with graphs with hundreds of node/edges.
Really nice. One nitpick: I can drag the graphs out of the svg frame and then they are lost forever. It would be nice if there was an attraction toward the center of the frame or there would be walls that wouldn't let this happen.
Cool. Any way I could connect my Neo4j API and visualize the db or individual requests?
Yes, this would be excellent. Most people who would be using this in a serious way would likely run the bulk of their queries on the serverside in their graph DB, and then perhaps allow a bit of graph manipulation in the browser just to visualize the results for users.
Some kind of hooking of a graph DB API would make this perfect.

Awesome! I'm currently piecing together teaching material for an intro to algorithms class and this is excellent. Right about to implement Bellman-Ford's and Dijkstra's.
I counted six cycles ?
6,7,8,6
8,0,3,4,9,8
0,5,1,0
0,1,3,0
(are these not considered separate cycles ?)
8,0,5,1,3,4,9,8
0,5,1,3,0
you're right hehe I should rename the problem to finding the number of back edges in the dfs tree, thanks for the feedback
Wow, this is slick!
Would love to use this to visualize a min/max algorithm.
A nice way to demonstrate graph algorithms, as you have already shown!

This is an entirely personal opinion, but as nice as it is, I find the font painfully difficult to read.
Indeed, I've changed the font, idk what I was thinking hehe
thanks for the submission OP!
no problem; thank you for something submission worthy.
love it!!
I am looking for a tool to construct a PERT visualization, but it require to be a activity-on-node type of graph
does Greuler allows to construct such type of graphs?

I'm sure you can do it, the layout is powered by WebCola which has an example of a DAG: http://marvl.infotech.monash.edu/webcola/examples/downwarded..., greuler is more like a tool that provides the necessary methods to interact with the nodes/edges of the graph in a nice way
