	Technical lineage graph	The actual visualization of the traceability of the current data object, according to your selection in the Browse tab pane. If you select a specific column in a table with multiple columns, you can click Collapsed columns [menu] to show all other columns, collapse all columns or only show selected columns in the same table. Tip Data objects that are stitched to assets in Data Catalog have a yellow background. Other data objects that the lineage harvester collected from your data source, but are not stitched and therefore are not assets in Data Catalog, have a gray background.
	Tab panes	Tab panes that contain useful tools to browse through your technical lineage or determine which content is visualized in the technical lineage.
	Browse tab pane	This pane can be used to search for specific data objects or show statistics on the amount of tables and views in use. More information.
	Settings tab pane	This pane can be used to search for transformation code, edit the visualization of the technical lineage, see the status of the source code, check the stitching results or export your technical lineage to PDF, PNG or CSV. More information.
	Source code pane	The source code pane shows the source code of specific data objects. It can be used to easily find issues in the data flow. The source code pane is shown when you click in the toolbar or when you right-click a column or table and click Transformations (IN) or Transformations (OUT) which shows the transformation logic in the source code pane.
