This animated scatter plot cycles through pairs of health metrics from a CSV dataset, showing relationships between age, BMI, health score, and steps per day. Each dot updates its position every two seconds as the axes shift to new variables. The visualization uses d3.csv for data loading, d3.scaleLinear for scaling, and d3.axisBottom/axisLeft with reusable scatterPlot function. SVG circles animate through the setInterval-driven updates, while axis labels dynamically change to reflect the current metrics.
