Dynamic Sublist mapping


I have generated a series of points that are ordered in a dynamic data tree.

{0;0}, {0;1}…
{1;0}, {1;1}…
{2;0}, {2;1}…

I would like to get at the point data within the nested list to draw individual longituninal lines between the points.

After the longitudinal points, transverse lines will then follow.

I can do the exercise in Grasshopper but I am floundering in Dynamo.

To add the dynamic aspect I would like to change the number of points and the lists and lines updating accordingly as I change the number of divisions.
