{"version":"1.0","type":"rich","title":"Life Expectancy – Similarity Network","description":"This interactive network visualization shows how countries compare in their life-expectancy trajectories from 2000 to 2023. Each node represents a country, sized by its final life-expectancy value and colored by geographic region. Edges connect countries with similar yearly patterns, computed using Pearson correlation within a user-selectable time window. The visualization uses `d3.forceSimulation` for layout, `d3.scaleOrdinal` for regional coloring, and a brushable year-range slider. Users can hover or click the color legend to highlight or filter regions, while a search box queries specific countries. An interactive legend supports multi-select filtering, and a tooltip displays details on demand.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/15f5084b0d484251b93d37c1177abd1a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
