create a clean vector style perforation pattern for an architectural aluminum facade screen the pattern should consist only of perfectly round circular holes with varying diameters approximately 6 30 mm in reality the circles create an abstract organic composition inspired by tree trunks reeds or flowing vegetation the design should contain large continuous negative spaces that read as soft vertical organic forms while the perforation density increases around these shapes the pattern should feel calm elegant and architectural not random requirements pure black and white only white background black circular holes only no gradients no shadows no textures no grey values no outlines no overlapping circles perfectly clean edges uniform spacing high contrast flat 2d graphic vector like appearance suitable for dxf or svg vector tracing composition vertical orientation seamless across multiple facade panels designed for an 8 m wide 16 m high facade continuous overall composition rather than repeating tiles elegant minimal contemporary architectural language similar to laser cut aluminum facade panels the final image should look like a professional perforated metal facade pattern ready for cnc laser cutting
