{"version":"1.0","type":"rich","title":"Heat Map","description":"This heat map visualizes a sequential color scale transitioning from purple to orange across a continuous spectrum. The view fills the browser window with 100 vertical rectangular bands, each colored via the `d3.scaleSequential` interpolator. The code uses `d3.interpolate` to blend the two colors, `d3.scaleLinear` for positioning, and SVG `<rect>` elements rendered with D3 v7. The example demonstrates how to construct a full-viewport gradient bar for quantitative data mapping.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/14d5fe4735a7494e95296432cb50ae81?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
