{"version":"1.0","type":"rich","title":"project1-plot","description":"This scatterplot visualizes the relationship between GDP per capita and happiness scores across 162 countries from 2015 to 2022, using data from a merged World Happiness Report CSV. Each circle represents a country-year observation, colored by year via `d3.scaleOrdinal` with `d3.schemeCategory10`, with a legend and interactive tooltips. The visualization uses D3 v7 with `d3.csv`, `d3.axisBottom`, and `d3.axisLeft` for axes, and SVG circles for marks. It is rendered as an animated, interactive SVG chart with hover-based tooltips displaying country, year, score, and GDP details.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/60f7720bf34e48b2b9e832a0bea44840?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
