A conceptual illustration of multiple brightly colored lines-blue, green, red, purple, and orange-converging into a pale yellow, translucent amorphous shape labeled "bottleneck" in bold sans-serif font, then diverging again. The lines vary in thickness and length, suggesting different flows or streams, with a slight digital sheen. Clean white background, studio lighting, even illumination, no shadows, high contrast, smooth gradients, crisp vector lines, symmetrical composition, eye-level perspective, wide shot, shallow depth of field emphasizing the bottleneck shape. Flat design, minimalist aesthetic, vibrant and optimistic mood, infographic style conveying constraint and release through information and process. Modern digital artwork resembling Adobe Illustrator, clean and professional presentation for educational materials.
