{"version":"1.0","type":"rich","title":"interactive Bubble chart - Engine","description":"This interactive bubble chart visualizes the relationship between engine displacement and fuel economy for a dataset of cars, sourced from a CSV file. Each bubble’s size encodes vehicle weight, while its color represents the number of cylinders. Built with D3 v7, the SVG chart uses `d3.scaleLinear`, `d3.scaleSqrt`, and `d3.scaleOrdinal` to map data to positions, radius, and color. Hovering a bubble triggers a tooltip, and the chart includes axes, gridlines, and a legend for filtering by cylinder count.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/db47881107744488af2ca092aa67e2f8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
