Scatter Plot with Missing Data
This scatter plot displays penguin bill length versus flipper length, filtering out any records with missing values in either dimension. The chart uses D3 to render axes, labels, and semi-transparent circles over a gray plotting area. The dataset comes from the `@curran/penguins` package, and the filtering logic leverages JavaScript’s `Array.filter` and the `isNaN` function to exclude incomplete rows, ensuring only fully observed data points are plotted.

const filteredData = data.filter(
(d) => !(isNaN(xValue(d)) || isNaN(yValue(d))),
);
