Popups
Popups, new in 1.2.1, offer a means for you to declaratively attach some component to act as a popup on a vertex, and as the user pans, zooms or drags the vertex, VisuallyJs will ensure that the popup remains in place relative to the element.

Configuration
Declare Component
Your component has access to:
- the vertex the popup is attached to
- the data model
- the UI that rendered this popup
- a function you can invoke to instruct the popup to hide
