{"version":"1.0","type":"rich","title":"activity-6_Task 1","description":"This example demonstrates a minimal Hello World page that displays a greeting message centered on the screen. It loads D3 v5 from UNPKG and uses the `d3.select` API to target the HTML `div#message` element, setting its text content to a string imported from a local ES6 module. The page renders static text only, with no data binding, interaction, or visual encoding beyond basic CSS styling for font size and alignment.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a174d9217b00459e9ee55e27f741946f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
