{"version":"1.0","type":"rich","title":"Clustered Bar Chart - Average Credit Card Utilization by Education Level","description":"This clustered bar chart compares average credit card utilization across six education levels, with blue bars for male customers and orange bars for females. The data comes from the Bank Customers Dataset, loaded via `d3.csv` and preprocessed using a custom `groupBy` function that aggregates transaction amounts by gender. The visualization uses `d3.scaleBand` for the x-axes, `d3.scaleLinear` for the y-axis, and `d3.scaleOrdinal` for color encoding. Bars are rendered as SVG rectangles within grouped elements, with axes generated through `d3.axisBottom` and `d3.axisLeft`, plus a legend appended dynamically.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6fa5ab323e6e4156bbc8375cf611e094?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
