This D3.js visualization provides an overview of a teams dataset loaded from a GitHub Gist, displaying dataset metrics (characters, columns, rows), a tabular preview of the first ten rows, and SVG circle swatches colored by each team’s hex code. The visualization uses `d3.csv` to parse the CSV and `d3.select` and `.append` to build both an HTML table and the circular color cards. The interface is styled with custom CSS, and the banner uses an SVG linear gradient fill.
