This interactive network visualization maps global life expectancy trends from 2000 to 2023. Each node represents a country, with its size proportional to the latest year's life expectancy and its color indicating geographic region. Edges connect countries whose life expectancy time series are most strongly correlated, based on Pearson correlation coefficients (top-K neighbors, thresholded by a minimum r-value). Users can drag nodes, pin them in place, search for specific countries, and filter by region via an interactive legend. The visualization, built with React and D3.js (d3.v7), uses a force-directed layout to position nodes dynamically.
