{"version":"1.0","type":"rich","title":"Concentric circles -linear gradient","description":"This example shows a field of concentric circles arranged around a central point, where each circle’s radius varies randomly and the overall composition suggests a glowing, planet-like form. The visualization is rendered as an SVG using React components, with each circle’s position calculated from trigonometric functions and a pixel-based loop. The code defines a radial gradient and a drop-shadow filter, while the background uses a CSS linear gradient from green to black. The `Circles` component receives `cx`, `cy`, `r`, and fill props, with random sizing and color values generated via JavaScript’s `Math.random()`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a47c903fa9984d64a577363881a0577f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
