How to avoid nodes overlapping when resizing?

[adriansimionescu83]

Hello everyone! 

I have a question concerning the rendering of layouts.

Here is the issue:

• First, I render a graph with the layout cose-bilkent. Nodes have different sizes
• The graph is correctly displayed (no overlapping of nodes)
• Then I resize each node programatically but I keep the current positions of each node: some nodes are now overlapping

I want to avoid overlapping. I know that I can rerender the graph by doing this.cy.layout(...).run() again. But by doing this, the graph will be rerendered totally, meaning the nodes could have a complete different position.

What I would like to have is a kind of update positions so that only in case there is a risk of overlapping, then the nodes move a little from their previous position to avoid as much as possible overlapping (the idea behind this request is not to confuse users: if the nodes have total different positions, it is hard for them to study the graph). I could not find anything in the documentation. Do you have an idea how to do it?

Thanks in advance for your help!
