{"version":"1.0","type":"rich","title":"Activity8_Q4","description":"This bubble chart maps GDP per capita on the x-axis and life expectancy on the y-axis, with circle size encoding population. Using D3 v4’s `d3.csv`, `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft`, it scales population from 200 to 2.11 billion to radii between 1 and 40 pixels. Circles are rendered via SVG with `stroke` and opacity styling, reading data from a gist-hosted CSV. The chart visually explores relationships between economic output, health outcomes, and country population.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6f5ee73315e440668049538af1487a3c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
