{"version":"1.0","type":"rich","title":"Ahmad's first Test","description":"This example displays a large “Hello, World!” message as the centerpiece of a minimal React and D3 visualization. The page renders the text inside an `h2` element using D3’s `select` and `append` methods, pulling the string from a custom `Handle` class defined in a separate module. The `Handle` constructor initializes x and y coordinates and provides a `draw` method returning the message. Styled with a 13em font size and centered via CSS, the visualization demonstrates basic integration of D3 selection with a React-based file structure, relying on d3.v5 for DOM manipulation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ac680168f2cd4132b7f847e24cd7a829?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
