This animated scatterplot cycles through the Iris dataset’s four measurements on the x-axis while keeping petal width on the y-axis. Colored circles distinguish the three species (setosa, versicolor, and virginica). The visualization is built with D3 v6, using `scaleLinear`, `axisBottom`, and `axisLeft` within a custom `scatterPlot` function. A `setInterval` triggers updates, re-rendering axes and labels every few seconds. SVG circle elements are colored via a switch statement, with legends and axis titles added dynamically, sourced from the CSV URL.
