{"version":"1.0","type":"rich","title":"Happiness Level Line Chart","description":"This interactive line chart visualizes self-reported life satisfaction across the world from 2004 to 2017, using data from the World Happiness Report 2017. A dropdown menu lets viewers switch between different happiness-related metrics, such as GDP per capita, social support, and freedom, with each selection redrawing the SVG line chart. Built with D3.js v5, it uses `scaleTime`, `scaleLinear`, axes, and a `line` generator with `curveBasis` to render smoothed paths. The visualization encodes the selected metric over time, revealing trends and patterns in global well-being.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c8281a0b2bdf4992b12f1da2dfffd6d9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
