For the Card Picker, I think a list of dictionaries is used.
The list contains 4 items (James Stuart - Training Manager, Isaac Pullman - Creative Director, Sarah Oscar - Sales Rep, Srinivas Tamada - Tech Lead).
Within each item in this list is a dictionary of four keys (phone number, home town, main role, photo).
The phone number is a number scalar.
The home town is a text scalar.
The main role is a longer text scalar.
The photo is a blob.
I think this is an effective visualization. It makes it easy to see the information of each employee without getting mixed up with the others.
To do less clicking, you could simply have a table or page where all the information is shown without having to press each person.
But I think this way allows you to have interaction with each member.
