Different size of the image - difficult to read any text or see dashed arrows

Hi,

Currently, I am drawing a graph with potentially a large number of points ordered as in a chessboard.

An example of coordinates of the nodes could be:
a) (0, 0)
b) (0, 1)
c) (1, 1)
c) (0, 2) etc

Below I suggest three possible developments that I believe would be interesting for the community.

1. As the number of points increase, size the plot is limited by a square plot with sizes 2.4x2.4, the distance between the nodes becomes soon so small that it is impossible to distinguish any text.
   A possible improvement would be to possibly specify a custom size of the map, not necessarily squared.

2. Moreover, let's suppose that there are 10 nodes in the x axis (all having y-coordinate 0 and increasing x-coordinates from 0 to 9), and let's suppose that there are 5 nodes in the y axis (all having x-coordinate 0 and increasing y-coordinates from 0 to 4).
   Given the current implementation, the spacing between the nodes having different x coordinate would be half the distance of nodes having different y-coordinate.
   In graphs representing geographical coordinates that would be quite ackward; it would be nice to specify options regarding the spacing between x- and y-axis, like equal (so that the spacing would be the same) or adaptive (in which all tha space would be used as in the current implementation)

What do you think?
