The hollow circle at a number means that this number is not included.
Example 1
x < 3
•-------•-------•--------о
0*****1*****2*******3
* is used as a spacer and has no significance otherwise.
Example 2
x ≤ 3
•-------•--------•---------•
*******1******2*******3

When you see this > or this <, don't fill in the circle.
But if it is greater than or equal to, fill it in (this just means that it is included in the graph).
