Cno cycle

A clean educational schematic icon of the carbon-nitrogen-oxygen fusion cycle shown as a compact circular reaction network. Small colored nucleus symbols or nodes are arranged in a closed loop and connected by curved directional arrows to indicate a repeating catalytic cycle. Carbon, nitrogen, and oxygen intermediates are distinguished by different colors, commonly dark gray, blue, red, or orange, with nuclei shown as simple spheres, clustered nucleus icons, or labeled isotope nodes. The overall layout is neat, ring-like, and clearly communicates hydrogen burning through the CNO cycle. Use thin, even line weight, flat colors, minimal shading, and a clean educational diagram style.
