{"version":"1.0","type":"rich","title":"gapminder demo","description":"This visualization reproduces the classic Gapminder bubble chart, plotting countries by GDP per capita (x-axis, log scale) and life expectancy (y-axis), with each bubble’s area encoding population and its color indicating region. The chart reads data from gapminder_avg.csv and renders as SVG using D3 v4. Hovering over a bubble likely reveals the country name, though the gist’s minimal files do not include an interactive tooltip. The example demonstrates how to load CSV data and map it to positioned, sized, and colored circles with axes, using the MIT-licensed d3.v4 code from almccon.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-b1e8d7030d8235b428142d262bf42b77?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
