{"version":"1.0","type":"rich","title":"An Exmple for D3.scaleSequential","description":"This example demonstrates how D3’s `scaleSequential` maps continuous numeric domains to color interpolators. It shows two rows of rectangles, each colored by a different sequential scale: one using `interpolateRdGy` and another using `interpolateReds`. The code uses `scaleSequential` with explicit domains and applies the resulting colors as SVG fill styles. A `scaleLinear` positions the rectangles horizontally, and black-outlined polygons mark a selected range. The visualization relies on D3 v5 and renders entirely as SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
