Show handles

Select a handle to edit it.

Handle value

Drag to move. Double-click empty space to add a random-valued handle. Select a handle and press Delete to remove it. Arrow keys move it.

New handles, spacing, handle seed, or handle value variance regenerate the handles.

Keep the handles fixed and try new draws. Randomness at zero gives the mean. Both views share a fixed color scale; strong overshoot clips the colors.
