When you say «visualize a single particle with lots of x-y-z coordinate.»
Do you mean a particle at a given coordinates from a list of 
coordinates, or a complex particle whose vertices are defined by those 
coordinates ?

In the first case, you simply iterate through the list of coordinates 
until you get to the desired ones and place some object there.
You may place some object at each set. Make them all transparent except 
the one that interest you.

In the second case, you need to generate a mesh from those coordinates, 
then, place it in your scene so that it can be rendered.
