Example from doc caues errors:

[lasotek]

Trying example:
lbls = ["Type A", "Type B"]
fig, ax, p = scatter(
rand(10), color = rand(1:2, 10), colormap = [:red, :blue],
inspector_label = (self, i, p) -> lbls[self.color[][i]]
)
DataInspector(fig)
fig

produce errors:

That probably means your Makie version is too old. This was added with Makie 0.18.0 (GLMakie 0.7)
