The code it becomes

What Studio writes for the graph below: a few lines of the material's shader, worked out for every pixel.

void mainImage(out vec4 fragColor, in vec2 fragCoord){    vec3 n2_colour = (0.5 + 0.5 * cos(6.28318531 * ((0.5 * 4.0 / max(normalize(vec3(0.0, 0.0, 1.0)).z, 0.2)) + vec3(0.0, 0.33, 0.67))));    fragColor = vec4(n2_colour, 1.0);}

Texture coordinates into the node, and the node into the material, as Studio draws them.
