{"version":"1.0","type":"rich","title":"1027Happiness Level Scatter Plot","description":"This scatter plot visualizes self-reported life satisfaction across countries from 2004 to 2017, using data from the World Happiness Report. A dropdown menu lets users switch between different well-being metrics on the y-axis, while each circle represents a country-year observation colored by country. The visualization combines a time-based scatter plot with overlaid line charts showing trends per country. Clicking a country in the color legend filters both the points and lines, with a tooltip revealing exact values on hover. The code uses D3 v5 APIs including `scaleTime`, `scaleOrdinal`, `nest`, `axisBottom`, and `transition().duration()` for smooth animations.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2d89bdcf26544decb2c23597759f3d85?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
