{"version":"1.0","type":"rich","title":"Vega-Lite Grouped Bar Chart","description":"This interactive visualization uses a grouped bar chart to compare average BMI between smokers and non-smokers across different regions, making adjacent bar comparisons straightforward. Built with Vega-Lite and rendered via the `vega-lite-api`, the visualization encodes region as columns, smoker status as x-axis and color, and average BMI as the y-axis. The data is loaded from a remote CSV using `d3.csv`, while custom axis styling removes domain lines and increases font sizes for readability. Tooltips display the average BMI on hover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b795a117340449dd9a11e052e3a7dc49?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
