{"version":"1.0","type":"rich","title":"Request and Response Drills","description":"Two interactive data-visualization drills demonstrate how request and response patterns shape real-time feedback. The first, a Mad Lib Generator, uses d3.forceSimulation to position user-supplied words as nodes, which respond to drag events with animated transitions. The second, an A/B Test, renders two competing button variants and logs click counts via a live-updating bar chart, drawing on d3.select and transition.attrTween for smooth state changes. Both examples rely on Glitch-hosted code and event-driven updates to show how user actions trigger immediate visual responses.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-7b1cf694b6c7671a918f544a06423295?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
