This scatter plot visualizes the Iris dataset, mapping petal width against sepal length, with each species represented by a distinct SVG symbol. Built as a reusable chart module using D3 v6, it employs `scaleLinear`, `axisLeft`, `axisBottom`, and `scaleOrdinal` for positioning and symbol encoding. The axes and points update dynamically every 15 seconds as the x-axis cycles through four measurement columns. The visualization uses an SVG rendering approach with animated transitions between attribute mappings.
