How would I perform an exploratory data analysis to visually assess the relationship between two sets of data?

I have two sets of data that look like this:

set 1: 184, 170, 332, 477, 165, 278, 188
set 2: 0.85, 0.75, 1.4, 2.5, 0.65, 1.1, 0.68

For the overall question, I am determining whether there is a relationship between these two sets of data using a simple linear regression model. But first, I have to perform an exploratory data analysis to visually assess the relationship between them. 

I think to do this I would have to use a scatter plot to visually see if there's a correlation between them - is this correct and/or is there anything else I should be doing?
