How are null values differentiated from empty strings in the recipe builder?

In the recipe builder, null values are specifically differentiated from empty strings by being marked in gray italics. This visual distinction is important because it provides clarity on the nature of the data being processed. A null value indicates the absence of a value, meaning that no data is present, while an empty string signifies that there is a value, albeit an empty one. The gray italics help users quickly identify null values among other types of data, allowing for better data management and manipulation throughout the analytics process.

Other formatting options, such as bold or red markings, are typically reserved for highlighting other types of data or errors in data input, making it crucial to have a specific style for null values, such as gray italics, to maintain consistency and understanding within the recipe builder environment.
