Starting My Data Viz Journey
This example shows a simple smiley face rendered as two black circles for eyes and a yellow circle with a black outline, set against a blank canvas. The visualization demonstrates the basics of SVG markup and styling with CSS, while also incorporating React for a minimal "Hello JSS" heading. The code loads React 16.7.0 via CDN, uses `ReactDOM.render` to mount the app, and relies on raw SVG elements like `circle` with attributes for positioning and appearance, alongside inline CSS to remove page margins and hide overflow.
