This bubble chart visualizes the correlations between sepal length, sepal width, and petal length in the Iris dataset. Each circle’s x-position represents sepal length, its y-position represents sepal width, and its radius encodes petal length. Species are distinguished by color using a categorical color scale. Built with D3 v7, the SVG visualization includes axis labels, a tooltip showing species and sepal dimensions on hover, and hover effects that adjust opacity and stroke width. Data comes from the included `bubblechart.csv` file.
