+Jupyter script that calls the Center for X-Ray Optics (CXRO) website [1] and retrieves the refractive index (tabulated values originally published by [2]) for a given material composition and density for low energies (30eV to 30keV).
+
+This script calls the website, retrieves the data and then plots it in either the typical delta and beta plot or the delta/beta ratio.
+The plots are interactive, so one can hover the mouse and easily retrieve the numerical values. It is also possible to also zoom and pan.
+A scroll bar that controls the material density allows the user to interactively investigate how different densities affect the refractive index.
+
+It also provides functionality for the differential refractive index (the refractive index for the boundary when you have a material inside another material).
