Plot.dot(
penguins,
Plot.dodgeY({
x: "culmen_length_mm",
symbol: (d) => (d.sex === "FEMALE" ? "square" : "star"),
tip: true
})
).plot({ height: 220 })
The [Object object] is the {draw: function} that corresponds to the symbol. Maybe it should just have a toString?

This is similar to a literal color channel. Perhaps the tip should ignore literal symbol channels too, since showing it again in the tip won’t help interpretation. The more idiomatic approach would be to define the channel as “sex” and then specify the domain and range of the symbol scale.
A channel of explicit symbols does not show in the tip nor has a legend
