This example visualizes the distribution of sepal length across three iris flower species—Setosa, Versicolor, and Virginica—using an area chart rendered on a Canvas element. The data is fetched from a remote CSV file stored in a GitHub Gist, parsed manually, and filtered by species. The chart is built with Chart.js, which uses the `fill` option to create semi-transparent filled areas under each line, with distinct colors for each species. The x-axis represents the flower index (1–50), while the y-axis shows sepal length in centimeters.
