{"version":"1.0","type":"rich","title":"Blank Canvas","description":"This example demonstrates fundamental DOM manipulation with D3.js by rendering an interactive smiley face whose eyebrows move. It shows how to select and modify SVG elements dynamically, creating a playful character that responds to browser dimensions. The code uses D3 v5's `select` and `arc` methods to construct shapes, with SVG attributes for width, height, and corner radius set programmatically. The visualization adapts to the full viewport size, with a fixed-position body and hidden overflow ensuring the canvas fills the entire screen.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/963995c6dfb84b15bd4735019de97b5a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
