More Information
The filter is used to display a more visual graphic in the Entries list rather than just the pure HTML value that is stored in the database.
Examples
The Rating field value is stored as an integer. If a reader provides a 4 out of 5-star rating, the value saved is in the entry is 4.
When viewing the entry information (entries table, single entry details) and when notification emails are generated, this filter converts the value and returns a visual representation,
/**
* Filter used to convert a given entry value to a more robust visual format.
*
* In this example, if a hex color code is given in a text value, it's converted
* to a link to view more details about the color.

* @param array $field The field.
* @param array $form_data Processed form settings/data, prepared to be used later.
