{"version":"1.0","type":"rich","title":"Activity_6 Q_4","description":"This bubble chart visualizes relationships between GDP per capita, life expectancy, and population across countries using the Gapminder dataset. Each circle represents a country, positioned on a logarithmic GDP axis and linear life-expectancy axis, with radius encoding population via `d3.scaleSqrt()` and color mapping continents through `d3.scaleOrdinal()` with `schemeTableau10`. Animated with D3 v7 `.transition()`, circles grow from radius zero to their final size over one second. The chart includes a legend for continents and axis labels, rendering as SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f1aa527dba364ea7aa5c07f1220b69bb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
