Well, the circle around a point is just a representation to show where the interval begins or ends.  When an open circle is used, it means "the interval starts immediately next to this point, but don't include this point."  When a closed circle is used, it means "the interval starts right here!"
Just consider the conditions you have.
  $$ x \ge number~(equal~to~number),~x \le number~(equal~to~number),~x < number,~x>number $$
