Smoothing error in Julia 1.10

[gyansinha]

Bug description

Smoothing example from documentation errors in Julia 1.10

Steps to reproduce

x = 1:0.05:10
a = rand(1:7, length(x))
y = sin.(x) .+ a .+ 0.1 .* randn.()
df = (; x, y, a)
specs = data(df) * mapping(:x, :y, color=:a => nonnumeric) * (smooth() + visual(Scatter))
draw(specs)
