{"version":"1.0","type":"rich","title":"Clustered Bar Chart - Credit Card Utilization by Attrition Status","description":"This interactive clustered bar chart visualizes credit card utilization from the Bank Customers Dataset, comparing the average of a selected metric (total transaction amount, credit limit, or revolving balance) across customer demographics. Bars are grouped by attrition status, with color distinguishing existing versus attrited customers, and dropdown menus let users switch between categorical groupings like income, education, or marital status. Built with D3.js, the chart uses `scaleBand` and `scaleLinear` for axes, `scaleOrdinal` for color encoding, and `transition` for smooth animated updates when the data selection changes. Tooltips reveal the underlying sum and count for each bar.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/58a0f64508a74969bbe78865c49b7216?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
