{"version":"1.0","type":"rich","title":"Mobility Rate Bubble Chart","description":"A bubble chart displays mobility rates for California universities, mapping median parent household income on the x-axis and mobility rate on the y-axis. Circle size encodes average cohort size, while color represents the trend in parents from the bottom 20% income bracket. The visualization includes average lines and selected labels. It uses D3.js v5 for rendering with an SVG canvas, implements scales via `d3.scaleLinear`, `d3.scaleSqrt`, and `d3.scaleDiverging`, and incorporates the d3-legend library for color and circle legends. Data is sourced from Opportunity Insights' Mobility Report Cards, filtered for California institutions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6dea447b6ae142e19aee68a027bea097?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
