{"version":"1.0","type":"rich","title":"Happiness Level Chart","description":"This visualization presents self-reported life satisfaction across countries from 2004 to 2017, using data from the World Happiness Report 2017. It combines a scatter plot with year and satisfaction metrics, a multi-line chart tracking trends per country, and an animated cartoon face that shifts expressions. Users select different satisfaction indicators via a dropdown menu and filter countries by clicking the color legend. The D3 v5 code builds SVG elements, uses scales like `scaleTime` and `scaleLinear`, and applies transitions to update data points and the face animation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/86132a2256864a898f2c63994bb71ae1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
