{"version":"1.0","type":"rich","title":"Activity_6_4","description":"This bubble chart visualizes gadget products by plotting price on the x-axis, quantity sold on the y-axis, and using bubble size to represent profit margin, with colors distinguishing product categories. The visualization loads CSV data from a GitHub repository and renders as SVG using d3.csv, scaleLinear, scaleSqrt, scaleOrdinal, and d3.axisBottom/axisLeft. A custom legend displays the categorical color mapping, while hover effects increase bubble opacity and add a stroke, making the chart interactive and readable.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2dc7d39b2df04c1bb88c1f10983e10c8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
