how do electric field lines appear when the field has the same strength at all points in a region?

This sounds like an impossibility to me.
By Coulomb's law, the strength of the field diminishes as a function of the square of the distance from the charge.
Maybe you need to give a clearer definition of what you mean by "region."
Each line is an indication of a single strength. For points to have the same strength, they would have to fall on the same line in the field. (Same as barometric pressure lines on a weather map.)

All the lines would be parallel.
The field strength is represented by the density (how bunched-together) the field lines are. If the strength changes from place to place, it means the lines are more spread out in some areas, and more bunched together in other areas.
If the field is uniform (same strength everywhere), the lines don't bunch together and spread apart like this. This is the same as saying the lines are parallel to each other.

You can't see the field lines, but if you draw reppresentations of them, you'd use straight arrows of the same size, the base would originate from the positive charges, and the tip of the arrow would point in to the negative charges.

You can't see them.
