Dear all,

When I use AlgebraOfGraphics.jl, How can I hide the legend title? Here is an example.

```julia
using RDatasets, AlgebraOfGraphics, CairoMakie
df = dataset("datasets", "iris")
plt = data(df) * mapping(:Species, :SepalLength, color = :Species) * visual(Violin)
fg = draw(plt; legend = (position = :bottom, titlevisible = false, framevisible = false))

```

How can I hide the legend title “Species”? I try to use `titlevisible = false`, but it does not work.

Just a guess but could you try `color = :Species => nothing`?

Oh yea, I think that (or an empty string) was the recommended workaround until a fix could be made upstream
