{"version":"1.0","type":"rich","title":"question4","description":"This bubble chart visualizes the relationship between vehicle type and fatalities for road incidents, with each circle’s size and vertical position encoding the fatality count. The visualization uses a categorical x-axis for vehicle types and a linear y-axis for fatalities. Built with D3 v7, the chart loads CSV data and renders SVG circles with steelblue fill and 70% opacity. Interactive tooltips display additional incident details, including severity and damage extent, when users hover over individual bubbles.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1dbd4c8e21074e48ba0dd3165b9f0711?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
