This interactive scatter plot visualizes the Iris dataset, allowing users to explore relationships between sepal and petal measurements. Two dropdown menus, implemented with React state, control which attribute appears on the x- and y-axes, with axis labels updating accordingly. The chart uses d3.scaleLinear to map data values to SVG coordinates, with reusable AxisBottom and AxisLeft components rendering ticks and grid lines. Each data point is drawn as a circle with an SVG title tooltip showing its hover value. The visualization is built with d3.v6 and React, loading data via d3.csv.
