This example displays a scatter plot of housing data, mapping living area (GrLivArea) on the x-axis against sale price (SalePrice) on the y-axis. Each data point is rendered as a small green circle using D3.js selections and the `append("circle")` method. The visualization loads a CSV dataset from a remote URL via `d3.csv`, and constructs linear scales with `d3.scaleLinear` to position the circles. Axes are generated using `d3.axisBottom` and `d3.axisLeft`. The plot is embedded within an HTML page styled with large, centered text.
