This interactive scatter plot of the Iris dataset lets users explore relationships between sepal and petal measurements. Clickable buttons select which two features appear on the x- and y-axes, highlighting the chosen dimensions in the control panel. The visualization uses D3 v5’s `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft` to render axes, with points colored by species (setosa, versicolor, virginica). Data loads from a CSV file containing 150 samples.
