[heatmap](http://makie.juliaplots.org/stable/plotting_functions.html#AbstractPlotting.heatmap) has a `heatmap(values)` function but there isn’t an example for it in the docs. How can I use it?

Found the answer in [an issue](https://github.com/JuliaPlots/Makie.jl/issues/748#issuecomment-769725523).

```julia
heatmap(rand(3, 3)) 

```
