In the last chapter, we created a static scatter plot. In this chapter, we'll make it interactive so that we can add, update, and delete runs. You'll learn how to do the following:

• Create a click handler
• Remove data
• Drag an element
• Update data after a drag
• Create a zoom behavior that scales elements
• Update axes when zooming/panning
• Update click points after a transform
• Avoid redrawing the entire screen during rendering
• Hide elements beyond axes
