This example presents a tabular preview and a suite of chart-based visualizations for a campus snacks dataset loaded from a CSV file. Using D3.js v7, it renders a bar chart, donut chart, scatter plot, and stacked charts directly into SVG elements, with a tooltip for interactions. The page also includes a U.S. map drawn with TopoJSON, loaded dynamically via the `topojson-client` library. Data is summarized and displayed across multiple chart types to explore patterns in the dataset.
