{"version":"1.0","type":"rich","title":"Mobility Rate Bubble Chart","description":"This visualization presents a bubble chart of mobility rates for universities in California, plotting median parent household income on the x-axis against the percentage of students from the bottom income quintile who reach the top quintile. Each bubble’s area encodes the average cohort size, while color diverges by the trend in parental income distribution. The code uses D3 v5 with d3.scaleSqrt for bubble sizing, d3.scaleDiverging for color, and the d3-legend library, filtering data from Opportunity Insights’ Mobility Report Cards. Averages are marked with dashed lines, and select institutions are labeled.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8ea82edeaa6d4eb19c8f2705a047c993?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
