With g9, making an interactive visualization is as easy as making a visualization that isn't.
Just write a function which draws shapes based on data, and g9 will automatically figure out how to manipulate that data when you drag the shapes around.
Example: An interactive dragon curve in under 40 lines of code. Try dragging the curve!
