{"version":"1.0","type":"rich","title":"sample","description":"This example shows a minimal D3.js starter template that renders the text “Hello D3” centered on a blank page. The visualization demonstrates basic DOM selection and content manipulation using the `d3.select` API, specifically targeting the `<body>` element and setting its text content. The code is structured as an ES6 module, importing `select` from D3 v7 via an import map in the HTML, and applies CSS styling for font size, alignment, and top margin. No data source is used; it serves purely as a foundational setup for D3 projects.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a373516ad9ec41caba8de8f90f5b7f82?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
