SIMPLE Ruby library for drawing shapes and managing clicks

Question

I am looking for simple library for Ruby that could help me drawing things on the screen. I am not developing a game, I just want to display some graphs, so I need to

• draw circles on a certain position,
• put a label on these circles,
• being notified that circle XYZ has been selected (I want to know the circle, not the coords),
• draw lines connecting circles' borders,
• change the color of the these circles,
• (optional) animate moving a circle from position (x1,y1) to (x2,y2) in X seconds,
• (even more optional) zoom on part of this scene.

Do you know anything that could help me with this?
