Plot legend with symbol scale example

[kmorozov]

In API docs there is info, that Plot can generate legends for color , opacity , and symbol scales. But I cannot find any example with last one. Could you make some simple demonstration how it works?

Yes, here is a basic example:

Plot.dot(penguins, {
  x: "body_mass",
  y: "bill_length",
  symbol: "island",
  fill: "island"
}).plot({symbol: {legend: true}})

As you can see when the color matches the symbol, the symbol legend carries both at the same time.
