We present Azimuthal Anisotropy Scaling Functions for identified particle species spanning beam energies from RHIC to the LHC. The scaling functions, which clarify the respective influence of initial-state eccentricity, expansion dynamics, and the transport coefficients, indicate characteristic signatures for the transport coefficient's dependencies on the temperature ($T$) and the baryon ($\mu_{B}$), strangeness ($\mu_{S}$), and isospin ($\mu_{I}$) chemical potentials. The extracted scaling coefficients indicate non-monotonic dependencies of the transport coefficients $\eta/s$ and $\hat{q}$ on $(T, \mu_{B})$, linked to the critical endpoint in the phase diagram for nuclear matter.
