 Plotting companion module for [ExtendableGrids.jl](https://github.com/j-fu/ExtendableGrids.jl)
-Provides grid and scalar piecewise linear function plotting for various plotting backends
+Provides plotting of grids,  scalar piecewise linear functions and vectors (2D only) for various plotting backends
 on simplicial grids in one, two or three space dimensions. The main supported backends
-are PyPlot, GLMakie and PlutoVista.

 ## Sample usage:
 
 ### Plotting a grid, a function or a vector field

-gridplot(grid, Plotter=PyPlot)

 This works for  1/2/3D grids and either a function  represented by its
 values on  the nodes of the  grid, or a scalar  function of 1, 2  or 3
-variables, respectively. Vector plots are currenly available for 2D only,
-and stream plots only for PyPlot.
