What would a good visualization of the Oort Cloud be?

Google results produce a spherical definition, and a disc-like definition. Which of these is more correct? To add to this, being able to "see" through the Oort cloud to other stars etc, what is the approximate density of the cloud? I know we can see out of our own, but when we look into other solar systems, is there any obscurity caused by its cloud? Does every solar system have one? Does it change over time?

The Oort cloud is a spherical collection of comets and other icy bodies at the very edge of our solar system. Gravity may have formed the bodies into a slightly greater density along the plane of the sun (and the planets) but observations of the cloud are scarce since it is so distant from us. It is different from the Kuiper belt in that it is much further out from the Sun, and contains either very long period comets or comets that do not move significantly from the cloud. The Kuiper belt is much closer, right outside the orbit of pluto, and contains larger bodies and shorter period comets. 

In terms of density, the Oort cloud is incredibly scattered. Looking out from the sun, it would be very unlikely that your view would be obscured by an Oort cloud object due simply to the tiny size of the objects and their distance from the us. For this reason, it is uncertain if there are Oort clouds in other solar systems. It is difficult enough to detect other planets in other solar systems, let alone small bits of ice that are on the order of thousands of AU from their star.
