About weighted graph support.

[frank-zsy]

Hello, lots of thanks for your great work on graph in js.

Here is question I've encountered in using these awesome projects. I am using pm to visualize some GitHub projects networks and it works fine right now but I need link weight support from the layout generation method.

I am using ngraph.offline.layout right now and I looked into the projects and I found that actually the physical simulator supports link weight/length in spring force calculation. But as this project is the basic data structure of ngraph and the type of addLink method only supports fromId, toId and data for custom data store.

Right now I need to do this as a work around:

(addLink(fromId, toId) as any).length = l;

Should I modify the interface to let users know that link length is supported already?

Thank you for your awesome work again~
