I'm not sure if the chart explains, although it can accurately point out what the relationship is.You are first cousins when you share the same grandparents, 2nd cousins if you share the same great-grandparents, 3rd cousins if you share the same great-great-grandparents, and so forth.
Whenever there is a difference in generation from the 1st or 2nd cousins, etc., that's when you have "removed".So you can have a 1st cousin (same grandparents) but if that cousin of yours has children, those children are your 1st cousin once removed.When those children have children of their own, they are your 1st cousins twice removed.
Same with 2nd cousins (same great-grandparents).When your 2nd cousin has children, they become once removed.If your 2nd cousins have grandchildren, those grandchildren are twice removed, so 2nd cousin once removed or 2nd cousin twice removed.
