{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example shows a smiley face created with D3.js, where circles are dynamically added to an SVG canvas based on an array of values passed to an `updateVis` function. The circles change color—red for values under 30 and blue for values above—demonstrating data-driven styling. Using D3 v5’s `select`, `selectAll`, `data`, and `enter` methods, the code appends `<circle>` elements with attributes for radius, position, and fill. The included `q3.csv` file provides a year-based running total dataset, though it is not referenced in the JavaScript logic shown.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5e1eb050f2fa4268843d1be5be09f180?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
