{"version":"1.0","type":"rich","title":"D3_React Smiley Hello HTML","description":"This example renders a simple yellow smiley face as an SVG graphic, composed of a circle for the head, two smaller circles for eyes, and a D3 arc path for the mouth. It is built with React 18 and D3 v7, using JSX to define the SVG elements and the `arc` generator from D3 to compute the mouth’s path. All coordinates are calculated relative to the center of a 960 by 500 viewport, and the graphic is rendered into the DOM via `ReactDOM.render`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
