CV = SD/Mean × 100%, SNR, index of dispersion — gauge SVG with variability bands, two-dataset comparison mode.

SNR = Mean/SD
Index of Dispersion Var/Mean
CV = (s/|x̄|) × 100%  ·  SNR = x̄/s  ·  I = s²/x̄
CV is unit-free — enables comparing variability across
datasets with different scales or units
