{"version":"1.0","type":"rich","title":"color palette generator","description":"This example presents a simple color palette generator using D3.js (v7) within an HTML page. It displays a circle and a series of five rectangles, each filled with a color interpolated along a linear scale from orange to black, using a gamma-corrected RGB interpolation with a value of 1.5. The visualization is rendered as SVG, with shapes positioned and colored based on the numeric scale values, demonstrating D3's `scaleLinear` and `interpolateRgb` APIs.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4ab2c83a1b584d0d8d04c07a30204f70?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
