{"version":"1.0","type":"rich","title":"SVG Injection","description":"This example demonstrates injecting HTML and SVG elements into a webpage using D3.js version 6. The code uses `d3.select` to target a div, appends a styled header, and creates an SVG canvas with a series of colorful circles. Each circle’s position, radius, and fill color are sequentially modified within a loop to produce a gradient-like visual effect. The example relies on D3’s `append` and `attr` methods, along with inline CSS styling, to render the final composition.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
