This animated scatter plot cycles through four different pairings of the Iris dataset’s numeric columns, using a reusable charting API built with D3’s `scaleLinear`, `extent`, `axisLeft`, and `axisBottom`. The SVG visualization updates every two seconds, re-mapping the x-axis to a new attribute while keeping the y-axis fixed. The code defines a configurable `scatterPlot` function with setters for data, dimensions, and value accessors, then applies it repeatedly to a full-window canvas with a custom font.
