{"version":"1.0","type":"rich","title":"Insurance","description":"The scatter plot shows medical insurance charges across patient ages, with points colored by smoking status to reveal that smokers incur consistently higher costs than non-smokers. The visualization uses the Vega-Lite API within a D3 v5 framework, binding CSV data loaded via `d3.csv` and rendering points with `vl.markPoint`. The chart encodes age and charges on quantitative axes via `vl.x().fieldQ()` and `vl.y().fieldQ()`, while the categorical smoker variable drives `vl.color().fieldN()`. Custom styling is applied through a Vega-Lite config object that adjusts axis labels and title fonts.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/750041c70761481b803c49fe4a5cae5a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
