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){    vec2 n1_uv = (vec2(fragCoord.x / iResolution.x, 1.0 - fragCoord.y / iResolution.y) * vec2(1.0, 1.0));    vec2 n1_centred = (vec2(fragCoord.x - 0.5 * iResolution.x, 0.5 * iResolution.y - fragCoord.y) / iResolution.y);    vec2 n1_square = (vec2(fragCoord.x, iResolution.y - fragCoord.y) / iResolution.y);    float n2_turns = fract(atan(((iPointer.xy - n1_uv) * vec2(iResolution.x / iResolution.y, 1.0)).y, ((iPointer.xy - n1_uv) * vec2(iResolution.x / iResolution.y, 1.0)).x) / 6.28318531);    float n2_distance = length(((iPointer.xy - n1_uv) * vec2(iResolution.x / iResolution.y, 1.0)));    fragColor = vec4(vec3(n2_turns), 1.0);}

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