Graph Area

At the top left of the Graph Area, a legend indicates the meaning of the node colors:

  • Subject: Main entities or key columns in the dataset.
  • Entity: Related objects or semantic concepts connected to Subjects.
  • Literal: Concrete values from the table (like strings, numbers, or dates).
Graph Area

You can explore and interact with the graph using the following actions:

  • Hover over a node to display its metadata.
  • Hover over a link to show its property and label.
  • Hide/Show link label to toggle between viewing just the property or both the property and the label when hovering over a link by clicking on the respective button in the top right.
  • Select a node to view its detailed information in the Sidebar and the corresponding data in the Column Values section.
  • Select a link to view its detailed information in the Sidebar.

Column Values

Located at the bottom left of the Graph Area, this section is tightly connected to node selection. Initially, the area displays a suggestion inviting the user to select a graph element. Once a node is selected, the table updates automatically to display the values of the corresponding column.

Suggestion

This view allows you to:

  • Inspect the actual data values associated with a semantic node, scrolling through the table.
  • Check the kind, role and types of a node by observing its content.
  • Identify patterns, repetitions, missing values, or inconsistencies in the data.
Column Values

The Column Values table acts as a bridge between the graph representation and the concrete data stored in the dataset, supporting both semantic analysis and data quality inspection.
