Sets the source reference on Chart Studio Cloud for `xbounds`.

Faster alternative to specifying `x` and `y` separately. If supplied, it must be a typed `Float32Array` array that represents points such that `xy[i * 2] = x[i]` and `xy[i * 2 + 1] = y[i]`

Sets the source reference on Chart Studio Cloud for `xy`.

Specify `ybounds` in the shape of `[yMin, yMax] to avoid looping through the `xy` typed array. Use it in conjunction with `xy` and `xbounds` for the performance benefits.

Sets the source reference on Chart Studio Cloud for `ybounds`.

*pointcloud* trace is deprecated! Please consider switching to the *scattergl* trace type. The data visualized as a point cloud set in `x` and `y` using the WebGl plotting engine.

If value is `snap` (the default), the node arrangement is assisted by automatic snapping of elements to preserve space between nodes specified via `nodepad`. If value is `perpendicular`, the nodes can only move along a line perpendicular to the flow. If value is `freeform`, the nodes can freely move on the plane. If value is `fixed`, the nodes are stationary.

If there is a layout grid, use the domain for this column in the grid for this sankey trace .

If there is a layout grid, use the domain for this row in the grid for this sankey trace .

Sets the horizontal domain of this sankey trace (in plot fraction).

Sets the vertical domain of this sankey trace (in plot fraction).

Determines which trace information appear on hover. If `none` or `skip` are set, no information is displayed upon hovering. But, if `none` is set, click and hover events are still fired. Note that this attribute is superseded by `node.hoverinfo` and `node.hoverinfo` for nodes and links respectively.

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 upper bound of the color domain.

Sets the lower bound of the color domain.

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