Prompt
"Create an image of a minimalist, symbolic representation of the Zermelo-Fraenkel set theory, using a combination of geometric shapes and mathematical notation. In the center of the image, depict a large, stylized set notation (e.g. a curly bracket) with various smaller sets and axioms branching out from it. Incorporate subtle visual elements that evoke a sense of hierarchy, such as nested circles or a tree-like structure, to convey the cumulative nature of the set theory. Use a clean, monochromatic color scheme with accents of bright blue or green to represent the axioms and sets. In the background, include a faint, gradient representation of a mathematical landscape, such as a graph or a geometric pattern, to evoke the connections to logic, model theory, and foundations of mathematics. The overall style should be abstract, yet precise and formal, conveying the rigor and beauty of the Zermelo-Fraenkel set theory."
