     If you want to keep type stability, it is recommended to use `Val(:two_dim)` and `Val(:three_dim)` instead of `:two_dim` and `:three_dim`, respectively. Also, specify the library as `Val(:CairoMakie)` See [this link](https://docs.julialang.org/en/v1/manual/performance-tips/#man-performance-value-type) and the [related Section](@ref doc:Type-Stability) about type stability for more details.
