This example uses Observable Plot 0.6.13 to render a symbol scatterplot of penguin measurements from the `@curran/penguins` dataset. It plots body mass against flipper length, with both the stroke color and symbol shape encoding the species. The plot includes a legend for symbols, a grid, and labeled axes. The chart is sized to its container and supports hot reloading by replacing the existing DOM node. The code imports from `@observablehq/plot` and uses the `Plot.dot` and `Plot.plot` APIs.
