Force simulation is jittery when using svg transforms to update position

JSFiddle example I've noticed that when updating positions of svg elements in a d3-force diagram, updating the positions of elements using (in the case of circles) the cx and cy attributes is much smoother than using the transform attribute. In the…

nodes without edges escaping the graph in D3 v4

I have built a graph that dynamically loads a few hundreds (sometimes thousands) nodes using D3.js V4. As much as I try to tune its forces, there are clusters of nodes that may get less cluttered, but consequentially the repel forces push nodes that…
