{"version":"1.0","type":"rich","title":"Loading data with React & D3","description":"A React and D3 example demonstrates asynchronous data loading by fetching a CSV of CSS named colors and displaying a summary message with file size, row count, and column count. The application uses React's `useState` and `useEffect` hooks to manage the data-fetching lifecycle, calling `d3.csv()` to parse the remote CSV file. Once loaded, the data is transformed through `d3.csvFormat` and rendered as SVG text. The visualization also includes a separate smiling face composed of reusable React components—`BackgroundCircle`, `Eyes`, and `Mouth`—where the mouth is drawn using D3's `arc()` path generator with specified angle parameters.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a396e79bda5f4fe7ba7772ce7abc39b4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
