Hi @mbostock. If I wanted to run this function outside of the Observable environment, what implication would `invalidation` have. As I understand it, this is an object that only exists in Observable.

Thanks. Beautiful graph, btw.

Harry

invalidation is optional; if you pass a promise, the function registers "simulation.stop" on this promise, so it can stop doing computations when it receives that message.

What's the point of 'replacing the input nodes and links with mutable objects for the simulation'

it would be great to give the option for node radius to insert and function to bind with data properties, as it is possibile for groups and titles

Michele Mauri

@Michele Great idea, I implemented it (you can now pass a function to nodeRadius).

@dianaow sorry for the belated reply: we need these objects to hold the changing values of x, y, vx, vy during the simulation (as well as fx, fy if the user holds a node manually with the pointer).

@Fil wow thank you! Anther useful variable to hadle with functions would be `linkStrength`, so as `linkStrokeWidth` you can bind it to data

Thanks for providing the notebook! 
I'm trying to use your code outside of observablehq in a "traditional html-javascript constellation". I'm importing D3 via a CDN. As promised, your function ForceGraph() returns a <svg> element. However, I'm failing to append it to the DOM. By listening to the event 'DOMContentLoaded' I make sure, that D3 can access my target element. Can you please give me hint, how to append the <svg> to the DOM?

Thanks in advance
Alexander

Alexander

Same issue on my side. I tried to append the created svg into my html by using: 

d3.select('body').append('chart');

But it looks it's still the wrong way to go. No graph appear in the web page but at least no error either.

Any hint how to do it?

Hervé

If _chart_ is the result of the chart cell above, you could try to use:
   d3.select('body').append(() => chart);

See https://github.com/d3/d3-selection#selection_append

Great! It did it, now the graph pops up in the web page.
Thx a lot for your help.
