{"version":"1.0","type":"rich","title":"gapminder with highlighting","description":"This example animates a Gapminder-style scatterplot of countries, plotting GDP per capita against life expectancy with circle size representing population and color indicating region. Hovering over a circle highlights it by turning it yellow and enlarging it via a transition, which then reverts on mouseout. Built with D3 v4, it uses `d3.scaleLinear`, `d3.scaleSqrt`, and `d3.scaleOrdinal` to map data to positions, radii, and colors, along with D3’s axis components. The visualization loads data from a CSV file and renders the interactive circles as SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-e591c4e1410665690d28098561feeacc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
