{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A smiley face rendered in SVG responds to mouse movement by shifting its eyebrows, demonstrating fundamental DOM manipulation with D3.js. The example uses D3 v5’s `select` method to target the SVG element and the `arc` generator to draw the face’s curved features, such as the mouth. The visualization shows how D3 binds data to existing DOM nodes without requiring `.enter()` or `.append()`, focusing instead on updating attributes in response to user interaction. The face is built entirely through SVG shapes, with styling handled by an external CSS file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7a57e270eec24890b7852f9673891f09?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
