This example demonstrates the basic setup for starting a D3.js project, displaying a numeric label as oversized text centered in the browser. The page renders a large number with a corresponding Greek letter name, such as "beta," based on a conditional mapping function. The code imports the `select` function from D3 v7 and uses plain JavaScript logic to assign labels, with the visualization relying on CSS styling for text formatting. The example includes a video tutorial reference and uses the `d3.min.js` library loaded from unpkg.
