Is The Same As

Is An Instance Of

A relationship in which one subject (A) is an illustrative case, example, or concretization of another (more abstract) subject (B). A is an instance of B. 

Is A Type Of

A relationship in which one subject (A) shares or exemplifies characteristics defined by another subject (B). Subject B is usually above the subject A hierarchically.

Example: A cat is a type of pet.

Is A Variation Of

A relationship in which two subjects share similar characteristics, but show deviations from each other. Unlike "is a type of", neither subject is above the other hierarchically.

Example: The Cesca chair designed by Marcel Breuer is in the public domain, so the design has been remade and remixed by several manufacturers. Each chair is a variation of the original.
