This visualization presents a compact summary of a cancer dataset loaded from an external CSV file. It displays key statistics—file size, row count, and column count—in a stylized, gradient-backed card with hover effects. The code uses D3 v7’s `d3.csv` to fetch and parse the data, then calculates the number of rows and columns dynamically from the parsed array. The summary updates the page content via standard DOM manipulation, providing a quick, visual overview of the dataset’s structure without additional charts.
