{"version":"1.0","type":"rich","title":"Making a bar chart","description":"Despite its title, this example does not render a bar chart. Instead, it demonstrates basic D3.js DOM manipulation by drawing a yellow smiley face with SVG shapes, including circles for the head and eyes, rectangles for eyebrows, and a path for the mouth. The code uses `d3.select` and `d3.arc` to build the shapes, then applies chained `transition().duration(2000)` calls on the eyebrows group to animate it moving down and back up over four seconds. The animation relies on D3's transition system to interpolate the `transform` attribute.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/72ad9afdf4ce4799b53bf9f85ba3ea55?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
