{"version":"1.0","type":"rich","title":"ACTIVITY6_T4","description":"This interactive bubble chart visualizes vehicle performance characteristics across 31 automotive brands, plotting horsepower on the x-axis, torque on the y-axis, and highway MPG encoded by bubble size. Each brand's bubbles are color-coded using d3.scaleOrdinal with the Tableau10 color scheme, with hover tooltips displaying exact values. Built with d3.v7, the visualization loads data from a local CSV file via d3.csv and uses d3.scaleLinear for all three encoding dimensions, rendered as SVG with axis labels, legend, and smooth hover transitions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a8b9d87d24e9414db4ffdd831bbd41bf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
