This example loads a CSV from a GitHub gist and uses `d3.csv` to fetch it, then displays the first ten rows of parsed data as JSON within a `pre` element appended to the body. It demonstrates importing D3 functions like `select`, `csv`, and `csvFormat` via a CDN and using local ES6 modules, with rendering handled through SVG and WebGL. The page also includes an embedded SVG background image and custom styling.
