This example presents a blank canvas as a placeholder for a D3.js "Hello World" exercise. It sets up an HTML page that imports the Share Tech font and CSS styling, while a JavaScript file uses the `select` function from D3 v6.7.0 to append an empty `div` to the body, sized to the full window dimensions. The code includes a separate `scatterPlot.js` module that defines a reusable scatter plot function using `scaleLinear`, `extent`, `axisLeft`, and `axisBottom`, but it is not invoked in this minimal example.
