{"version":"1.0","type":"rich","title":"Activity6_Task4_Q4(9)","description":"This bubble chart visualizes airline performance by plotting total passengers on the x-axis, fleet size on the y-axis, and using bubble radius to encode on-time performance percentage. The chart uses a categorical color scale to distinguish airlines, with an SVG legend positioned to the right. Interactive tooltips appear on hover using a custom HTML overlay that follows the mouse. Built with D3 v7, the visualization reads CSV data and configures axes, scales, and event handlers through the D3 API.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b3d1acd5a1674f80999876a05a9328f0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
