This visualization presents a scatter plot matrix of the Iris flower dataset, with each pair of the four numeric variables (sepal and petal length and width) displayed as separate small multiples. The diagonal cells show histograms of each variable’s distribution, while off-diagonal cells show scatter plots colored by species using `d3.scaleOrdinal`. Built with `d3.scalePoint` to position each cell, `d3.scaleLinear` for axes, and `d3.axisBottom`/`d3.axisLeft` for ticks, it uses `d3.extent` to compute per-cell domains and the `d3.histogram` API to bin data for the diagonal plots. Data is loaded as CSV from a remote URL, rendered as SVG circles and rectangles.
