In this example we’ve used following nodes to visualize different types of DataContainer object with SURFACE3D node.

• PLOTLY_DATASET: This node returns a DataFrame.

• Matrix: This node returns Matrix type DataContainer object.

• DF_2_ORDEREDTRIPLE: This is a type casting node, that converts DataFrame to OrderedTriple type of DataContainer class.

• ORDERED_TRIPLE_2_SURFACE: This node converts OrderedTriple to Surface type of DataContainer class.
