Blender for some reason doesn’t include a method to spread out all the objects of your selection so you can view them. So here is a quick snippet that will spread all of your selection across the X axis:

import bpy

# Starting offset
offset = 0
# Distance between the objects
distance = 3

for obj in bpy.context.selected_objects:
    obj.location.x = offset
    offset += distance + obj.dimensions.x

Paste that into a new script in the Scripting tab, select the objects you want to distribute, and hit the Play button.

Just a little snippet to make life a bit easier - enjoy!
