{"version":"1.0","type":"rich","title":"dv.30 - react starter code","description":"This example demonstrates a minimal React application that renders a green full-screen background with the text “hello react.” The code loads React 16.9, ReactDOM, and D3 v5 from CDNs, then uses `ReactDOM.render` to mount a functional component called `App` into a `
` element. The component returns a plain JSX div, showing how to set up a basic React environment with D3 available for future visualization work. The styling applies a light green background and removes default margins.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
