+
+To add a Lens visualization to a comment within your case:
+
+. Click the *Visualization* button. The Add visualization dialog appears. 
+. Select an existing visualization from your Visualize Library or create a new visualization.
+
++
+
+IMPORTANT: Set an absolute time range for your visualization. This ensures your visualization doesn't change over time after you save it to your case and provides important context for other viewers.
+
++
+. Save the visualization to your Visualize Library by clicking the *Save to library* button (optional).
+.. Enter a title and description for the visualization. 
+.. Choose whether you want to keep the *Update panel on Security* activated. This option is activated by default and automatically adds the visualization to your Visualize Library.
+. After you've finished creating your visualization, click *Save and return* to go back to your case.
+. Click *Preview* to see how the visualization will appear in the case comment.
+. Click *Add Comment* to add the visualization to your case. 
+
+NOTE: Once a visualization has been added to a case, it cannot be modified or deleted. However, you can interact with the visualization by clicking the *Open Visualization* option in the comment menu.
