{"version":"1.0","type":"rich","title":"Activity 6 Question 4","description":"This bubble chart visualizes airline ticket sales data from a CSV, plotting the number of routes on the x-axis against average ticket price on the y-axis. Each circle’s area encodes passenger volume, while color distinguishes airlines, with a legend and interactive tooltips showing exact values. The visualization uses D3 v7’s `scaleLinear`, `scaleSqrt`, and `scaleOrdinal` APIs to map data dimensions to visual encodings, rendered as SVG circles. Animated tooltips appear on hover, and the chart includes labeled axes and a title, all built with D3’s selection and layout methods.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/69a432b14d2f471aa6d5c9335a7f6693?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
