According to my research the graphics pipeline works like this:
Model Space
-> * Scalation/Translation/Rotation Matrices
World Space
-> * View Matrix
View/Camera Space
-> * Perspective Projection Matrix
Clip Space
-----> gives you NDC which are used by Rasterization
Could someone tell me if this is correct?
Is Clip Space the same as Projection Space?
That's correct, but you are focusing only on the vertex shader stage. I think this is a more general overview of a "graphics pipeline". That is what OpenGL offers you, however you don't need to use all stages, some stages are optional. A typical program will only use a vertex (Model=>World=>View=>...) and a fragment shader(texturing, lighting,...).
Moreover, you should note that your pipeline is a rasterizer pipeline. There are other methods (Ray tracing).
