Update Canvas Properties
You can use the canvas properties dialog to perform many different tasks. For example, add a description to display as a tooltip, change the layout, set brushing, synchronize visualizations, configure canvas refresh settings, and specify the background color and image.
You can also toggle grid settings and layout positioning options for a
                        canvas. See Align Visualizations Using Canvas Grid Guidelines.
