Each city’s bubble uses a distinct color from the `d3.interpolateTurbo` scale and is positioned using `d3.scaleLinear`. Hovering reveals a tooltip with city name and GDP. A legend displays GDP values, with circle sizes corresponding to the `z` scale. Data comes from `bubblechart.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e9aa656a8a314cc3a8506f546f54f898?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
