{"version":"1.0","type":"rich","title":"Task8_Turorial 4","description":"This interactive bubble chart shows the correlation between average horsepower, torque, and highway MPG for various car makes. Each circle’s position encodes horsepower on the x-axis and torque on the y-axis, while its radius and color represent highway MPG and car brand, respectively. The chart is rendered as SVG with D3 v7, using `d3.scaleLinear` for axes and bubble size, `d3.scaleOrdinal` for color, and `d3.axisBottom` and `d3.axisLeft` for ticks. A tooltip displays the car make on hover, and legends annotate bubble size and brand colors. Data comes from a CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/feccd9bafa8c4b269dddbb10e775c8f9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
