{"version":"1.0","type":"rich","title":"Scatter Plot with gradient mask","description":"A full-screen scatter plot displays 2,000 random points individually as white circles, revealing a large red-to-blue linear gradient only through the circular gaps. The random point coordinates are generated with a custom `generateRandomPoints` function. The code applies the gradient to a single circle, then defines an SVG `<mask>` containing the white point circles to cut the gradient shape, demonstrating mask-based data visualization with d3 v6.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5190172dd1a5441e887c60bbbadd95a9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
