{"version":"1.0","type":"rich","title":"Activity6_Question4","description":"This bubble chart visualizes product data from a CSV file, plotting price on the x-axis against quantity sold on the y-axis. Each circle’s radius represents profit margin using `d3.scaleSqrt`, while color encodes the product category through `d3.scaleOrdinal` with `d3.schemeTableau10`. The SVG rendering uses `d3.axisBottom`, `d3.axisLeft`, and the `d3.select` and `.enter()` APIs to draw circles, with a custom HTML legend positioned in the upper right corner.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5aecb66209ee456eb69d0e6c30572daa?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
