{"version":"1.0","type":"rich","title":"Fork Question4-Bubble chart","description":"This bubble chart visualizes the correlation between GDP per capita, life expectancy, and population-area ratio for 20 countries. Each circle represents a country, with its x-axis position reflecting GDP per capita, y-axis position reflecting life expectancy, and bubble size proportional to population density. The chart uses D3.js v7 with the `scaleLinear` API for axis and bubble scaling, and the `scaleOrdinal` API for color assignment. Interactive tooltips display precise country data on hover, while an SVG-based legend identifies each nation’s color.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5c71aea6f79e417d8e9bf22a952a45b8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
