{"version":"1.0","type":"rich","title":"Making a bar chart","description":"This example demonstrates fundamental DOM manipulation with D3.js by constructing a yellow smiley face whose eyebrows animate up and down. An SVG circle forms the face, with additional circles for eyes and a path created using the `d3.arc` function for the mouth. The eyebrows are rectangles that move via `transition.attr` to shift their vertical position over time. The code uses selections like `select` and `append` to build the SVG hierarchy, with a two-second duration for each eyebrow movement.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f092555555724113afe16ba24a57844a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
