{"version":"1.0","type":"rich","title":"Fork of Hello HTML","description":"This example demonstrates how to create a masked SVG visualization using vanilla JavaScript and React. It renders an SVG canvas with a circular mask centered on the screen, then draws a series of vertical rectangles that are clipped by the mask. The code uses the `createElementNS` API to build SVG elements dynamically, along with the `mask` and `rect` elements to achieve the visual effect, with React serving as the framework for the page structure.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
