Assemble Graph

Format data in Visual Notebooks so it can be used with a Graph node.

Configuration

Field	Description
Name default=`Assemble Graph`	A user-specified node name displayed in the workspace
Select Column with Vertex ids Required	Vertex IDs
Select the column in the vertices dataset that contains the vertex IDs.
Select Source Columns Required	Source column
Select the column in the edges dataset that contains the source of each relationship.
Select Destination Column Required	Destination column
Select the column in the edges dataset that contains the destination of each relationship.

Input	A dataframe with vertices data and a dataframe with edges data
Output	Vertices and edges data that can be used with a Graph node

Example output

Figure 1: Example output

Connect a dataset with vertices and a dataset with edges to an Assemble Graph node. Ideally, these are separate datasets. If the datasets are not separate, arrange the data so all the IDs are in the same column.
- The dataframes shown below are used in this example. The "people.csv" data contains a list of people and their ages. This data is used as vertices. The "relationships.csv" data contains a list of connections between the people, as well as a "weight" column that quantifies the strength of each relationship. This data is used as edges.

Example edges dataset

Select the "person" column for the "Select Column with Vertex ids" field.
Select the "source" column for the "Select Source Columns" field, and select the "target" column for the "Select Destination Columns" field.
Select "Run" to format the data so it can be used for a graph.
- Use the tabs near the top to toggle between the vertices and edges. Notice that Visual Notebooks makes some slight changes to the input data.
- This output can be connected to a Graph node.
