This animated scatterplot cycles through four Iris flower measurements (petal width, sepal width, petal length, sepal length) on the x-axis while keeping sepal length on the y-axis, using D3’s `scaleLinear`, `axisLeft`, `axisBottom`, and `csv` loader to update axes and points every few seconds. The Iris dataset is loaded from a remote CSV file, and each species is color-coded (setosa in sky blue, versicolor in light green, virginica in orange) with a custom legend. The visualization runs as an SVG animation, rebuilding the plot and its labels with each interval trigger.
