Using VB6 to create addin for MS WORD

[mathprof]

Could someone outline the steps I must take to create an 'object' for MS Word 2000?
I want to be able to 'insert' my object just like MS Chart is inserted.
I notice that in MS Word 2000 I can click on insert, object, then create FROM FILE.

I want to create an object which will print a grid with X&Y axes, graph a function like f(x)=x^2-6x and then insert the whole thing as a picture.

I can do the programming but I'm fuzzy on the object creation.

Thanks.
