{"version":"1.0","type":"rich","title":"Homework 4","description":"A brushable scatter plot matrix of the Iris dataset displays pairwise relationships among sepal and petal measurements, colored by species. The code builds on D3 v7’s `d3.cross` for the grid, `d3.scaleOrdinal` with `d3.schemeTableau10` for category colors, and a custom histogram using `d3.histogram` and `flatGroup` for stacked bins.
