Hello,  
is there a way to implement text annotations using mapping() ?  
If possible I would like to know how to annotate text at the bottom or tip of little thin arrows.  
If not possible withing AoG, I would like to know how to do it with the help of Makie.  
I tried to find this information in the web but couldn’t solve it.  
Thank you very much.

Should be `mapping(:x, :y, text = :text) * visual(Text)`, the signature of `Text` is now similar to `Scatter` et al. Maybe with `:text => verbatim` if AoG wants to convert it to numbers otherwise.

Thank you both. It gives me error when I write  
`*visual(Text):`

```julia
type ERROR: UndefVarError: Text not defined
Stacktrace:

 [2] top-level scope
   @ /mnt/md1/mmestre/work/2022/RiosDelCosmos/footprints/galstreams.jl:117
or paste code here

```

Besides this issue, how could I annotate with text+little arrows?  
Thanks.

Makie.Text then, I think Base has a Text as well.
