Correlation and line chart


Question: Why can’t we see the above line chart to give conclusion to CORRELATION between 2 variables?
I read somewhere which states that :" we use the line chart which can give wrong conclusion to correlation between 2 variables, and we should use scatter plot"

Where is this exhibit?

Here is location where this exhibit comes from.
Source: CFA prerequesite curriculum - Quantitative - Module: Organizing, visualizing, and describing data.

Thanks.

I’ll take a look at it when I have a moment.
