 - Visualization of these grids and of functions on them is avaialable in [GridVisualize.jl](https://github.com/j-fu/GridVisualize.jl).
 - [SimplexGridFactory](https://github.com/j-fu/SimplexGridFactory.jl) contains an API which allows to
   create `ExtendableGrid` objects with  [Triangulate.jl](https://github.com/JuliaGeometry/Triangulate.jl) which wraps the Triangle mesh generator
