1. A graph display device comprising:
a display unit;
an operation unit; and
at least one processor,
wherein the at least one processor is configured to
display, on the display unit, a two-dimensional graph formula displaying tag which displays a two-dimensional graph formula including two variables, a three-dimensional graph formula displaying tag which displays a three-dimensional graph formula including three variables, and a three-dimensional graph displaying tag which displays a first three-dimensional graph corresponding to the three-dimensional graph formula,
move the two-dimensional graph formula displaying tag based on an operation of the operation unit under a condition where the two-dimensional graph formula displaying tag, the three-dimensional graph formula displaying tag and the three-dimensional graph displaying tag are displayed,
upon detecting that the two-dimensional graph formula displaying tag is displayed to be superimposed on at least a part of the three-dimensional graph formula displaying tag as a result of the moving of the two-dimensional graph formula displaying tag, perform conversion of the two-dimensional graph formula displayed on the two-dimensional graph formula displaying tag to a three-dimensional graph formula corresponding to the two-dimensional graph formula, and
display, on the three-dimensional graph displaying tag, a second three-dimensional graph corresponding to the converted three-dimensional graph formula together with the first three-dimensional graph corresponding to the three-dimensional graph formula displayed on the three-dimensional graph formula displaying tag.
