This interactive visualization uses the Iris dataset to explore relationships between sepal and petal measurements. Two scatter plots are shown side by side, each displaying a different pair of attributes (sepal length vs. sepal width, and petal length vs. petal width). Points are colored by species. A distinctive feature is that brushing (clicking and dragging to select a region) in one plot automatically zooms the other plot to the corresponding points, enabling linked exploration of the dataset. The visualization is built with D3 v3, renders in SVG, and loads the data from a CSV file with metadata describing variable types and labels.
