These "dots" indicate the different connecting points or parts of a situation. "Connect the dots" is a well-known phrase that metaphroically means to join together different pieces of information and points to make one big idea or scenario. It comes from the children's game "Connect the Dots," where one literally connects dots on a piece of paper with lines to form a picture. Ex: I used to love playing Connect the Dots! Ex: When I got the email, I was finally able to connect the dots. Ex: You have to connect the dots to understand the whole movie.
