{"version":"1.0","type":"rich","title":"Vega-Lite Grouped Bar Chart","description":"This grouped bar chart compares average BMI between smokers and non-smokers across different regions, using adjacent bars for each smoker status to make direct visual comparisons easier. The visualization loads medical cost data from a CSV file via d3.csv and renders with Vega-Lite, using the vega-lite-api to encode columns by region, x-axis by smoker status, and y-axis by average BMI. The color channel also maps to smoker status, and a tooltip displays the average BMI on hover. Display settings are customized through a config object that adjusts font sizes and axis styling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/11009424ae224c068cf784d5459a7e4c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
