{"version":"1.0","type":"rich","title":"Iterated Clustered Bar Chart - Average Credit Card Utilization by Education Level","description":"This clustered bar chart visualizes average credit card utilization by education level and gender, using data from the Bank Customers Dataset. Six education categories are shown on the x-axis, with male and female averages paired as blue and orange bars respectively on the y-axis. The D3 code groups raw records via a custom `groupBy` function, then renders SVG rectangles with `scaleBand` and `scaleLinear`. Interactive tooltips display the total transaction sum and record count per group, while hover effects temporarily darken bar colors. Axes are formatted with `axisBottom` and `axisLeft`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/85bf35bde73c40d4ba314ddef634fb7a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
