node.label.prefix

: String. Adds a prefix to the node label

node.colors

: String | named list. Color for the node. Can be 'rgba(120,32,14,1)', '#97C2FC' (hexa notation on 7 char without transparency) or 'red'. Can be just one color, or a list with several elements:

1. "background" : String. Default to '#97C2FC'. Background color for the node.

2. "border" : String. Default to '#2B7CE9'. Border color for the node.

3. "highlight" : String | named list, Color of the node when selected.

   1. "background" : String. Default to '#97C2FC'. Background color for the node when selected.

   2. "border" : String. Default to '#2B7CE9'. Border color for the node when selected.

node.font

Node Font : Array. Example list(color = "black", face="Arial")

node.size

Integer. Node Size.

edges.smooth

: Boolean. When true, the edge is drawn as a dynamic quadratic bezier curve.

edges.dashes

: Array or Boolean. Default to false. When true, the edge will be drawn as a dashed line.

edges.colors

: Named list or String. Default to named list. Color information of the edge in every situation. Can be 'rgba(120,32,14,1)', '#97C2FC' (hexa notation on 7 char without transparency) or 'red'.

• "color" : String. Default to '#848484. The color of the edge when it is not selected or hovered over (assuming hover is enabled in the interaction module).

• "highlight " : String. Default to '#848484'. The color the edge when it is selected.

• "hover" : String. Default to '#848484'. The color the edge when the mouse hovers over it (assuming hover is enabled in the interaction module).

• "inherit" : String or Boolean. Default to 'from'. When color, highlight or hover are defined, inherit is set to false! Supported options are: true, false, 'from','to','both'.

• "opacity" : Number. Default to 1.0. It can be useful to set the opacity of an edge without manually changing all the colors. The allowed range of the opacity option is between 0 and 1.

edges.width

: Number. Default to 1. Sets edge width.

options.highlightNearest

: Boolean. Default to true. Highlight nearest when clicking a node.

options.nodesIdSelection

: Boolean. Default to false. Add an id node selection creating an HTML select element.
