That’s a mistake.

“To visualise his point, he …” would mean that he did something so that he himself could visualise the point. It does not fit this context where he is doing something so that others can understand the point. It would be possible to say “To help us visualise his point, he showed us five charts…”

The tenses “showed” and “get” do not match in this sentence.
