How to render each vertex of graph smoothly step by step with a small delay (like animation)? Modern OpenGL

  animation, c++, opengl, shader, vertex

I’m not sure that I formulated this question correctly, but I need any help possible. Currently I am creating a small programm for rendering trajectory path in real time. Entry data is array of vertex positions (x, y and z coordinates) and texture coordinats. When I compile the programm it renders the whole graph, I want to render it smoothly, like an animation, when every vertex (or pixel) appears with a small delay. Is it possible?

I am really new to openGL and only recently started learning it.
