This interactive scatter plot visualizes the Iris flower dataset, allowing users to explore relationships between sepal and petal measurements. Three species are distinguished by color, with data points smoothly animating to new positions when the axis selection changes. The visualization uses D3 v5's `scaleLinear`, `axisBottom`, and `axisLeft` APIs to render the plot, alongside a custom dropdown menu system. The chart transitions circle positions using `transition().duration(1000)`, with SVG rendering for all graphical elements.
