3D plotting is commonly used in nanotechnology to visualize the spatial arrangement of atoms in a crystalline lattice or to represent the shape and size of nanoscale particles. For example, scanning tunneling microscopy (STM) and atomic force microscopy (AFM) generate data that can be plotted in 3D to show the topography of a material's surface at the atomic level. These plots help in understanding the surface roughness, defects, and other critical features.
