{"version":"1.0","type":"rich","title":"1027Happiness Level Line Chart","description":"This visualization displays self-reported life satisfaction across countries from 2004 to 2017, using a scatter plot where each circle represents a country-year observation. Users select a metric from a dropdown menu, and clicking a color legend entry highlights that country’s points while dimming others. The D3.js v5 code employs `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and transitions to animate marks, with `interpolateRdYlBu` for color encoding. Data originates from the World Happiness Report 2017, rendered as an SVG with interactive legend and dropdown functionality.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a38ebb9cc9d84ee8b81d660cec73ef82?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
