{"version":"1.0","type":"rich","title":"Activity6Task-4","description":"A bubble chart displays three quantitative variables from a CSV dataset, mapping x and y coordinates to axes and a third size column to circle radius. The D3.js v7 code creates an SVG container with linear scales for position and size, then renders semi-transparent circles using data-bound enter selections. Axes are added via d3.axisBottom and d3.axisLeft, with labels for the X and Y axes, producing a straightforward scatterplot-style visualization with bubble sizing.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bf2c3de19cea44a2a5bff6fc00a20b31?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
