{"version":"1.0","type":"rich","title":"Blank Canvas!","description":"This example demonstrates fundamental DOM manipulation with D3.js by rendering a smiley face whose eyebrows move. It first uses `d3.select` to target the SVG element, sets its dimensions based on the viewport, and appends a rounded rectangle as the canvas background. The code relies on basic SVG attributes like `width`, `height`, and `rx`, while the interactive eyebrow animation is driven by D3’s data-binding and update patterns, though the specific motion logic is not shown. The visualization highlights how D3 can directly control SVG structure from JavaScript.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6091ffc6594b4329a4e9f48d39079ad0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
