Is there a way to dynamically generate line intersection graphs that have an area shaded in?

Yes. Look at the examples in setGeometry4SubsetsOfR2. For example the command

$graph1->fillRegion([1,1,'yellow']);

fills the region containing (1,1) with yellow. Here is a more dynamic example

$graph2->fillRegion([1,$fill_point_y,'yellow']);
