Shiny app for plotting Laser ICPMS and EMPA maps. More generally the app can plot heat maps and spatial data that has consistent spacing between x and y coordinates. The underlying plot function uses the ggplot2::geom_spatial() geom.
Color palletes are derived from the viridis family, developed to offer a more inclusive (color blindness) and realistic color scheme.
This shiny app uses functions from the geochem package https://github.com/muhohl/geochem
