This interactive scatterplot demonstrates a reusable D3 component that visualizes the Iris dataset, cycling through different combinations of sepal and petal measurements every two seconds. The chart animates smoothly as the x-axis, y-axis, and point radius change between variable pairings, using D3's transition API for the morphing effect. The implementation builds a custom `scatterPlot` function that leverages `scaleLinear`, `scaleSqrt`, and `axisBottom`/`axisLeft` to render axes, while the join operation handles circle updates and transitions. The JavaScript code fetches the CSV data from a GitHub gist and binds it to the plot's configurable `xValue`, `yValue`, and `radius` properties, showing how D3’s modular design supports adaptable, data-driven visualizations.
