This reusable scatter plot visualizes room measurements from the Iris dataset, with each point’s shape encoding species and axes dynamically cycling through four numeric columns every 15 seconds. Built with D3 v6, it uses `scaleLinear`, `scaleOrdinal`, `symbol`, `axisLeft`, `axisBottom`, and `join` for SVG rendering. The chart animates by resetting its x-value accessor and re-invoking the chart function, demonstrating the reusable chart pattern.
