{"version":"1.0","type":"rich","title":"Gubs Intro course","description":"This visualization displays dummy survey data for groups A through D, using black circles to represent each group’s total count with area proportional to the value via `d3.scaleSqrt`, while opacity encodes the total relative to 50. Group labels appear centered within each circle as white text. Built with D3 v7 and React, the SVG rendering positions circles horizontally with a fixed spacing, and the code demonstrates basic data binding with `selectAll().data().join()` for both circles and text elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5f6689b611164f2992c4b99204149527?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
