This example loads a user-supplied raw CSV file and presents a data summary alongside a preview table of the first ten rows. The D3 v7 code uses `d3.csvParse` with `d3.autoType` to parse the data, then computes column-level statistics such as minimum, maximum, mean, and unique value counts. A static SVG picture demonstrates five basic shapes—rectangle, circle, polygon, line, and text—styled via external CSS. The interface includes a text input and button for fetching new data URLs, with results rendered into the summary and table containers.
