• Expand: You can expand one or more selected vertices to fetch n-hop neighbors.

  To expand a vertex, click on the specific vertex and click the Expand option in the toolbar. Alternatively, you can right-click on the vertex and click Expand in the context menu.

  The following figure illustrates expanding on vertex 289.

• Focus: You can drop everything in your visualization and fetch n-hop neighbors of one or more selected vertices.

  To focus on a vertex, click on the specific vertex and click the Focus option in the toolbar. Alternatively, you can right-click on the vertex and click Focus in the context menu.

  The following figure illustrates focused visualization on vertex 934.

• Group: You can group selected vertices and collapse them into a single one.

  To group vertices, select multiple vertices and click the Group option in the toolbar. Alternatively, you can right-click on the selection and click Group in the context menu.

  The following figure illustrates grouping of vertices 287, 590, 934, and 289.

• Ungroup: You can ungroup a group of selected vertices.

  To ungroup, select the group and click the ungroup option in the toolbar. Alternatively, you can right-click on the group and click ungroup in the context menu.

  The following figure illustrates ungrouping of vertices 287, 590, 934, and 289.
