This bubble chart visualizes the correlation between sepal length, sepal width, and petal length across three iris species. Each circle’s x-position represents sepal length, y-position represents sepal width, and radius encodes petal length, with color distinguishing species. The visualization uses d3.csv to load the dataset, d3.scaleLinear for axes and bubble sizing, and d3.scaleOrdinal with d3.schemeCategory10 for species colors. Tooltips appear on hover, and a legend explains both bubble sizes and species categories. The SVG rendering approach includes interactive mouse events for enhanced exploration.
