Hello. Can anyone please tell me what I’m doing wrong here? I just want to draw a circle at the point (1,2), but I can’t find any circle, ellipse or rectangle drawing commands in Makie.

```
julia> using GLMakie
julia> function fred()
# Plot the simplex axes:
fig = Figure(fontsize=24)
axis = Axis(fig[1, 1])
scatter!( axis, [1], [2], markercolor=:green, markersize=15)
fig
end
fred (generic function with 1 method)
julia> fred()
Error showing value of type Figure:
