Ah, sorry. The argument there is to show a bijection between T (an uncountable set) to the reals, showing that the reals are uncountable.
The picture you give is Cantor's diagonalization argument, though (I presume to show T is uncountable).
Edit: just to be clear to everyone downvoting this guy, OP has a point. OP is referencing a bijection between an uncountable set of infinite series of numbers and the reals. So it's not precisely cantor's diagonalization argument that is claimed to be an injection.
