{"version":"1.0","type":"rich","title":"D3 Starter - Asynchronus","description":"This example demonstrates asynchronous programming in JavaScript using Promise objects and the `setTimeout` API, showing how to handle operations that take time to complete. The code defines a `waitSeconds` function that returns a Promise resolving after a specified delay, then chains `.then()` to log a message once the time has elapsed. Using D3 v6 loaded from a CDN, the page includes explanatory text about asynchronous versus synchronous behavior, with no data visualization or rendering involved—the focus is purely on illustrating the callback and Promise patterns.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7c73493a62b84b9a8bc1cd92a6d70ec4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
