{"version":"1.0","type":"rich","title":"Episode 4","description":"This example displays the text “Hello D3 version 7” centered on a blank page in a very large font size. It demonstrates a minimal setup for using D3 version 7, showing how to select a DOM element and replace its text content with a string. The code imports the `select` function from the `d3` module and applies it to the `body` element, setting its `text` property to the greeting. The page loads the D3 library from a CDN and runs the logic from a bundled script.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
