Building points in Java with interaction

Question

I have a large number of data points, which are two-dimensional coordinates with non-integer values ​​(float). I am looking for a Java library that can help me build these points, allowing me to customize the size, color, and labels of the points. In addition, I would like the user to be able to interact with panning and zooming points, and I want to be able to capture KeyEvents from the user.

Processing is great for what I want, but I don't want to do everything from scratch. Is there a better solution?

Thanks in advance.

Edit: There are about 2k points.

This example handles thousands of nodes easily.

GraphPanel() {
    ...
    Random rnd = new Random();
    for (int i = 0; i < 2000; i++) {
        Point p = new Point(rnd.nextInt(WIDE), rnd.nextInt(HIGH));
        nodes.add(new Node(p, 4, Color.blue, kind));
    }
}
