Fork of D3 Starter

This example demonstrates the minimal setup required to render text with D3 version 7. It shows the string "Hello D3 version 7" centered on a blank page, using a 13em font size. The code imports the `select` function from the D3 library and applies it to the document body to set the text content, leveraging the library's DOM manipulation API. The page loads D3 from the unpkg CDN and the custom script from a local bundle.

Parallel Coordinate Plot

This parallel coordinate plot displays sample data across four dimensions, A through D, with each row represented as a polyline connecting its values on parallel vertical axes. The code builds the chart using D3 v7, employing `d3.scalePoint` to position axes and `d3.axisLeft` for tick marks, while polylines are drawn with `d3.line` and SVG paths. The provided dataset, `users.csv`, is not actually loaded; instead, the visualization uses hardcoded sample arrays for demonstration purposes.
