This D3.js (v7) example displays a dataset summary and table preview, rendering statistical badges and a styled HTML table from a remote CSV file. It uses `d3.csv` to fetch the data, then computes column names, numeric columns, and distinct city/category counts to generate the badge texts. The code builds the table by appending `<th>` and `<td>` elements via D3’s selection and `.enter()` pattern, and concludes with a static SVG badge composed of a filled rounded rectangle and centered text. The visualization emphasizes data structure and quick previews within a clean, card-based layout.
