This example demonstrates a student data dashboard that loads a CSV file containing student names, ID numbers, color codes, favorite subjects, and team names. It displays summary statistics for total students, unique subjects, and unique teams, alongside a bar chart showing team membership counts rendered with D3 v7's `d3.rollups` and `scaleBand`/`scaleLinear` APIs. The page also features color swatch cards and a preview table, with data fetched via the `d3.csv` method and custom canvas rendering for the SVG bar chart.
