This visualization demonstrates a scatter plot exploring relationships between heart rate and steps, using the Iris Dataset as its foundation. The plot animates every two seconds, cycling through different column pairings to reveal various correlations. Built with D3 v6, it employs modular, reusable chart functions including `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to render interactive SVG circles. The code dynamically updates the x-axis mapping via `setInterval`, showcasing the flexibility of D3’s join pattern for smooth transitions between data dimensions.
