This example displays a library book dataset summary and a static SVG illustration. It fetches CSV data from a user-provided URL and uses D3.js version 7 to parse and analyze the columns, categorizing them as numeric or categorical and computing statistics like min, max, and mean. The summary section lists row and column counts, while a separate SVG image shows five basic shapes (rectangle, circle, polygon, line, and text), utilizing D3's `d3.csvParse` and aggregation functions.
