hierarchical layout too wide on initial

[farseerfc]

Hi I am using vis.js to build a package virtualizer: https://github.com/farseerfc/pacvis/
I found it very hard to stabilize when there are more than 100 nodes. I tried to disable physics and found that the initial layout by hierarchical layout engine is too wide for 100 nodes. I created a jsfiddle:

Here is a hierarchical layout only 74 nodes with custom levels, and physics is disabled. On my screen I can see the resulted image like this:

If I add more nodes, the initial layout became too wide to stabilize by physics. How can I fix this?

Edit:
Found out that I can remove this line https://github.com/almende/vis/blob/master/lib/network/modules/LayoutEngine.js#L868 and this line https://github.com/almende/vis/blob/master/lib/network/modules/LayoutEngine.js#L870 , then the layout worked as desired and I can scale to more than 1000 nodes with physics enabled.
