| A point can depend on another geometric object. This dependence can be given by using JavaScript syntax or by using
| |
| GEONExT syntax. Here is an example using GEONExT syntax.
| |
| The point A is draggable. The point B depends on point A: Its y-coordinate is set to 1 and its x-coordinate is set
| |
| to the x-coordinate of A.
