{"version":"1.0","type":"rich","title":"Activity6_Task4 ","description":"This bubble chart example visualizes data from a CSV file, encoding two quantitative variables as plot positions and point sizes. The implementation uses the D3.js library’s scale functions and SVG circle elements. The code reads `bubblechart.csv` to load the underlying dataset, then maps rows to circles whose x/y coordinates and radii reflect measured values. The rendering relies on standard SVG coordinate attributes and D3’s data-binding methods. The interactive viewport is set up with a fixed width and height.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1861e939262c4f3c96f03e2129c652c7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
