Each cell pairs two variables, with diagonal labels and interactive features including tooltips on hover and brush-based selection that highlights data points across all panels. The visualization is built with D3 v7, using d3.csv to load data, d3.scaleLinear for axes, and d3.brush for filtering, all rendered as SVG elements with circle markers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/27317807edba40c7a4cc3013f0210394?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
