Links labeling

Hello! Is there any possibility to add labels to links? I’d like to have structure like that:

links: [
    {source: x, target: y, relationship: "xxx"}
]

And I want to create something like I have in my neo4j browser:

If not label, at least I’d like to have different colors, like we can do with nodes, simply by adding “color: value” to the node object.

If there are no plans for features like that, maybe some tips how I can implement them?
