reproduce v3 simulation under v4 about d3-force

Sorry, but that’s too much code for me to debug. If you can create a smaller example that demonstrates an issue, I can take another look, but there could be many reasons why your code isn’t working and it’s too time-consuming for me to debug a large amount of unfamiliar code.

It’s hard to tell because you’re using the minified version of D3, but it looks like the nodes and links that you are passing to d3.forceSimulation and d3.forceLink, respectively, are selections rather than data. I think you meant to pass arg.nodes and arg.links instead.

I just hoped it would be something obvious.

Pretty ignorant I guess I mixed up data an selection because I got an exception using args.nodes and args.links and not with nodes and links. With a fresher head I now figured out how to fix the problems I ran into with this loop in d3.v4.js.

I'll play around again for a while before I collect the courage to create a smaller example.
Thanks for having a look.

You did spot the problem. I kept mixing things up but finally tackled it. Thanks again.

How did you manage to do it? I am also struggling to replicate exact force layout in d3 version v4 as I did in version 3 of d3?

The conversation above explains the essential mistakes I made with the new API. You don't get slapped on your wrist for mistakes so it required some debugging to figure out where I mixed up things.

Then behavior still was a bit different, so I tweaked the parameters until I got something that pleased me more than the original behavior. So no I did not replicate exactly the original force layout.
