{"version":"1.0","type":"rich","title":"HW4-311553050","description":"This scatter plot matrix visualizes the Iris dataset, showing pairwise relationships between four flower measurements. The diagonal cells display histograms of each individual attribute, while off-diagonal cells show scatter plots colored by species, using orange, teal, and purple to distinguish Iris setosa, versicolor, and virginica. Users can brush a rectangular region in any cell to highlight corresponding data points across all other scatter plots, with brushed circles turning gray. The visualization is built with D3.js v3, using `d3.svg.brush`, `d3.histogram`, and linear scales, rendering as SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f24a46b6b0f943abbef38656b6496c93?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
