Fork of Scatter Plot with Missing Data
This example shows a scatter plot of penguin measurements, plotting bill length against flipper length. Missing data is filtered out before rendering so that only complete observations are drawn as semi-transparent circles. The code uses D3’s `select` and `scaleLinear`, along with `Array.filter` and `isNaN` to remove rows with undefined values. The chart includes axes, labels, and a gray inner rectangle, with data sourced from the `@curran/penguins` dataset.
