How to quickly draw a graph?

Question

Java

Decided to make a graph in Java, got this:

[GraphPoint{x=-3, y=9}, GraphPoint{x=-2, y=4}, GraphPoint{x=-1, y=1}, GraphPoint{x=0, y=0}, GraphPoint{x=1, y=1}, GraphPoint{x=2, y=4}, GraphPoint{x=3, y=9}]

Function: y = x*x

In general, how to draw a graph from these points, something like this:

Only without any show-offs by the type of coordinate numbers, just a graph and points on it

The java charting library request mostly references the JFreeChart library. If this is not quite what you need, there is also a video "JavaFX | How to plot functions?". As an approach - you can probably use it in Swing.
