This visualization demonstrates how to integrate a Google Calendar date picker into a Yii PHP application using the GCalendar extension widget. It shows the widget configured to bind to a model attribute named `date_of_birth`, with the date format set to `dd/mm/yyyy`. The code instantiates the GCalendar widget, passing the model and input field parameters to enable date selection within a form. The extension handles the calendar UI and populates the specified input field with the formatted date value.
