{"version":"1.0","type":"rich","title":"Mobility Rate Bubble Chart","description":"A bubble chart displays mobility rates for California universities, plotting median parent household income against mobility rate (the percentage of students from the bottom income quintile reaching the top). Circle size encodes average cohort size, while color represents the trend in parents from the bottom 40%. The visualization uses D3.js v5 with `d3.scaleSqrt` for bubble sizing, `d3.scaleDiverging` for color, and `d3-legend` for legends. Data comes from Opportunity Insights' Mobility Report Cards dataset, filtered to California institutions, with labels for select universities.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/38a1f8ae1e524056b062cd2afa37f82d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
