  locked = TRUE,
  animation = list(duration = 1500, easingFunction = "easeInOutQuad")
)

Arguments

graph

id

: a node id

scale

: Optional. Number. The scale is the target zoomlevel. Default value is 2.0.

offset

: Optional. List. The offset (in DOM units) is how many pixels from the center the view is focussed. Default value is list(x = 0, y = 0).
