Hello Ben, very helpful video! Can you tell me how to vary the link distances? i get my data (links and nodes) from a json file where i specified the lengths but i can't use them as the linkDistance. any suggestions? Thanks in advance!
Hey man. I have been working with D3 for past few days. I wanted to create a simulation of a distributed network in D3. I can understand how I can make nodes and links between them. But how do I visualize the signals that are passed between them. I want a small ball to move along on the link from one node to another when a data or signal is passed between those two nodes. Please help me out here. Thanks.
How to make the spawn location the center? Right now, they seem to spawn at random places but when there are a lot of nodes, it looks really glitchy and jarring.
Hi, am trying to build a desktop standalone app with electron 4 GUI and python doing the work. How do i parse a networkx json graph using flask and collect it in electron using d3.js to render the graph
Hi, thanks for this great tutorial, I really loved how simple and straight forward it is. I am wondering, giving the current links data structure, why didn't you do the following: links.forEach(function (link) { nodes[link.source] = {name: link.source}; nodes[link.target] = {name: link.source}; });
I didn't test it but I believe that might duplicate some of the nodes. This snippet for creating the links is pretty common and should be more resilient bsaed on diff data coming in.
In what a scenario would it cause duplication. I tested Ahmed's suggestion for a simple example and it worked fine. I'm trying to create a scenario when it breaks but haven't figured it out so far.
Hi Ben, In this section of code, why do you first show 'links.source', but the second clause is 'link.target' ? links is the external and link is the internal var. is this a typo?
For those looking: force.layout has changed to .forceSimulation in D3 v5+

Awesome tutorial man, I was stuck on mapping the links to nodes all day yesterday
thanks!
Hi Ben, Kindly share the project with us please ;) Great tutorial man!
really important to use specially for transportation data.

Hi , I want to show a communication graph between two group , how can I achieve this .... I was trying with ngx-graph
Hi Ben, Really good tutorial, Thanks!!. how do I mark edges/links with arrow instead of plain?
Is there an updated version of this? Thanks
I haven’t made one but I’m sure there are tutorials out there

Hi can you make a video on disjoint force-directed graph . Thanks
Uncaught TypeError: Cannot read property 'force' of undefined
You might be using D3 v4, in which case d3.layout.force() becomes d3.forceSimulation()
@@mingmingrr1 thanks for that, helped me out
and version v5 ?
How do I put name on each node? (Based on the data in source)
Hi there! Have u found out how to do this? :)
Tell me how please and how to right next to the links
Great!

aha, I tested it and it looks bad suggestion, you are right, sorry for that.
