Specification

Aggregation

Graph Chart aggregates a weight (metric) for each combination of source and target (dimensions) and draws the relationships between nodes.

Item	Role	Notes
Source	Dimension	The node the connection originates from.
Target	Dimension	The node the connection points to.
Weight	Metric	Reflected in edge thickness or node size.

Examples

• Show "number of page transitions" as a Sankey diagram.
  • Source: the page transitioned from.
  • Target: the page transitioned to.
  • Weight: sum of transition counts.
• Show "mentions between social media users" as a graph.
  • Source: the mentioning user.
  • Target: the mentioned user.
  • Weight: sum of mention counts.

Specification by drawing type

Graph

• Turning on Undirected graph treats the connection between source and target as bidirectional, merging A→B and B→A into one.
• Link node color to weight changes node color based on the node's weight.

Sankey

• The direction of flow is drawn visually.
• If the data contains a circular reference, the chart can't be drawn, and the message "The data contains a circular reference, so it can't be drawn as a Sankey diagram" is shown.

Tips

Frame

Graph Chart supports the frame feature. See Frame for details.
