Groups of nodes. Each group is defined by an array with the indices of the nodes it contains. Multiple groups can be specified.

The normalized horizontal position of the node.

The normalized vertical position of the node.

Sets the `node` color. It can be a single value, or an array for specifying color for each `node`. If `node.color` is omitted, then the default `Plotly` color palette will be cycled through to have a variety of colors. These defaults are not fully opaque, to allow some visibility of what is beneath the node.

Sets the color of the `line` around each `node`.

Sets the width (in px) of the `line` around each `node`.

Sets the padding (in px) between the `nodes`.

Sets the thickness (in px) of the `nodes`.

Determines which trace information appear when hovering nodes. If `none` or `skip` are set, no information is displayed upon hovering. But, if `none` is set, click and hover events are still fired.

Sets the source reference on Chart Studio Cloud for  label .

Sets the `link` color. It can be a single value, or an array for specifying color for each `link`. If `link.color` is omitted, then by default, a translucent grey link will be used.

Sets the color of the `line` around each `link`.

Sets the width (in px) of the `line` around each `link`.

An integer number `[0..nodes.length - 1]` that represents the source node.

An integer number `[0..nodes.length - 1]` that represents the target node.

A numeric value representing the flow volume value.

Determines which trace information appear when hovering links. If `none` or `skip` are set, no information is displayed upon hovering. But, if `none` is set, click and hover events are still fired.

The label of the links to color based on their concentration within a flow.

Sets the upper bound of the color domain.

Sets the lower bound of the color domain.

Sets the source reference on Chart Studio Cloud for  source .

Sets the source reference on Chart Studio Cloud for  target .

An indicator is used to visualize a single `value` along with some contextual information such as `steps` or a `threshold`, using a combination of three visual elements: a number, a delta, and/or a gauge. Deltas are taken with respect to a `reference`. Gauges can be either angular or bullet (aka linear) gauges.
