This scatter plot visualizes the Iris dataset, mapping glucose and blood pressure measurements. Built as a reusable D3 chart, it uses `scaleLinear`, `axisLeft`, `axisBottom`, and SVG circles to render points. The chart cycles through various columns—such as Insulin, BMI, and BloodPressure—every two seconds, updating the x-axis and point positions via `setInterval`. Data loads from a CSV URL, and the visualization includes animated transitions between different variable comparisons.
