The d Orbitals

The five real l = 2 spherical harmonics dz2, dxz, dyz, dx2-y2 and dxy, each multiplied by the nodeless 3d radial factor and drawn as an isosurface at 0.220 of its own maximum |psi|. One isovalue and one scale are used across all five, laid out two, one, two with dz2 centred. Colour carries the sign of the lobe.
