 ### Chaining figure operations
 With the exception of property assignment, all of the figure update operations described in this section are methods that return a reference to the figure being modified.  This makes it possible the chain multiple figure modification operations together into a single expression.
 
-Here is an example of a chained expression that creates a faceted scatter plot with OLS trend lines using plotly express, adds a title using `update_layout`, disables vertical grid lines using `update_xaxes`, updates the width and dash pattern of the trend lines using `update_traces`, and then displays the figure using `show`.
