{"version":"1.0","type":"rich","title":"Activity6_question 3","description":"This scatter plot visualizes World Happiness Report data from 2015–2023, comparing GDP per capita against happiness scores for three selected countries: the United States, Japan, and India. Each circle represents a yearly observation, colored by country via a categorical color scale. The visualization uses D3 v6 to load CSV data from a GitHub repository, with axes rendered using `axisBottom` and `axisLeft`, and scales defined through `scaleLinear` and `scaleOrdinal`. A custom legend, built with SVG rectangles and text, identifies the countries, while the plot dynamically sizes to the browser window.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b9df8397073840a995af0f5c4e141e4b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
