renderCallback fires too early?

[magjac]

I want to access the "transform" attribute of the second level g element in the svg, but it is not available immediately after calling renderer.render(). I tried to use the renderer.renderHandler() callback, but it fires before the attributes are available.

Is this intentionally? If so, is there some other way to know when the rendering is finished?

Below is my log file. It shows the following timeline:

19:13:14.207: rendering starts 19:13:14.583: callback fires 19:13:14.658: renderer, stage & layout-worker have all returned, but the attributes are not available yet 19:13:14.762: attributes becomes available 19:13:15.494: attributes are stable (D3 animation has finished)
