This interactive bubble chart visualizes the Iris dataset, plotting sepal length against sepal width for three species of iris. Each circle's size is scaled to the flower's petal length, and its color indicates the species, with a legend identifying the categories. Built with D3.js v7, the SVG chart uses `d3.scaleLinear` for axes and bubble scaling, `d3.scaleOrdinal` with `d3.schemeCategory10` for colors, and displays a tooltip on mouseover, revealing species and sepal measurements. The visualization is rendered with an animation framework and supports hover interactions.
