{"version":"1.0","type":"rich","title":"Line Plot of Life Expectancy Data_GDPVsLifeExpectancy","description":"This line plot shows life expectancy versus GDP per capita across multiple years, with each line representing a year colored by a category scale and line thickness reflecting average BMI. The visualization reveals a logarithmic relationship where higher GDP correlates with increased life expectancy, though gains diminish at higher income levels. Built with D3 v4 and Metrics-Graphics, it loads CSV data from a GitHub gist and nests rows by year to generate separate series. Hovering over a line displays the exact year, GDP, and life expectancy values through the chart’s interactive tooltip.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/04e3eba11d474a9b95500b338824a331?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
