{"version":"1.0","type":"rich","title":"activity 6 task 4","description":"This interactive bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 31 car makes. Each circle represents a make, positioned by horsepower on the x-axis and torque on the y-axis, with bubble size encoding highway MPG and color distinguishing car brands via `d3.scaleOrdinal`. Hovering reveals a tooltip with the make name. The visualization uses SVG rendering with `d3.axisBottom`, `d3.axisLeft`, and `d3.scaleLinear` for scales, plus a custom legend for size and color. Data comes from the bundled `bubblechart.csv` file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/329295fc86a14fca8253a008977a1d33?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
