This bubble chart visualizes the Iris dataset, plotting sepal length against sepal width for 150 flowers. Each circle's size encodes petal length, while its color distinguishes the three species, with a legend mapping categorical colors. The SVG rendering uses D3 v7 scales for positioning and sizing, with a tooltip that displays species and sepal measurements on hover. The implementation shows no animation, only static circles with interactive mouse events, despite the metadata noting animation support.
