Study a Variety of Famous Gems

Famous gems can be used to demonstrate the usefulness of "chaining". This is the ability to use one property value to perform deeper data exploration, perhaps into other domains than where you start from. When a property value is an Entity, you can explore the properties of that entity. This can be done by nesting EntityValue calls to obtain the property values of successfully deeper calls.

The result is in a different domain. You can ask for the Bravais lattices of the cubic crystal system to see what variants exist.

This can be encapsulated in a single call that also goes further and returns a visual representation.

Even without chaining, you can find a few interesting facts about famous gems. For example, you can plot the cut versus uncut weight of famous gems.

Group gems based on their mineral type.
