This example sets up a blank white SVG canvas for a visualization titled "UEFA Prediction Viz." The code initializes a D3.js scene using `d3.select` and a declarative `.join` workflow to create the root SVG element sized to the container. It defines a small data array containing country and group fields, but the commented-out code reveals an intended node-based chart, likely a scatterplot or network, with attributes for position, radius, fill, and opacity. As written, the visualization renders no visible marks; it only establishes the rendering scaffold using D3 version 7.8.5.
