{"version":"1.0","type":"rich","title":"Mobility Rate Bubble Chart","description":"This bubble chart displays the relationship between median parent household income and mobility rate for universities in California, with each circle's area representing average cohort size and color indicating changes in the percentage of parents from the bottom 40% of income distribution. Data comes from Opportunity Insights’ Mobility Report Cards dataset. The visualization uses D3.js v5 and d3-legend to render an SVG, employing `d3.scaleLinear` for the x and y axes, `d3.scaleSqrt` for circle radius, and `d3.scaleDiverging` with `d3.interpolatePiYG` for color. Average lines and labels for selected institutions are also drawn.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8f1cff1b00b943ee8ea87f5eadb316b3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
