{"version":"1.0","type":"rich","title":"Activity6-Q4.9 2","description":"This bubble chart shows the relationship between electric car brands and their maximum price in euros. Each bubble’s vertical position and size encode the price, while color uses a plasma gradient to provide an additional visual cue. The chart is built with D3 v7, using the `d3.csv` loader to fetch data, `d3.group` and `d3.max` to aggregate by brand, and `d3.scaleBand`, `d3.scaleLinear`, `d3.scaleSqrt`, and `d3.scaleSequential` for the scales. Axes are drawn with `d3.axisBottom` and `d3.axisLeft`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bdeca135fcb641af93717ddf9d7e22b1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
