This scatter plot visualizes the relationship between ground living area and sales price for apartments, with each data point rendered as a semi-transparent green circle. The chart uses D3 v5’s `scaleLinear` for both axes, `extent` to compute domains, `axisLeft` and `axisBottom` for labeled axes with gridlines, and an SVG group to position the marks. Data is loaded from a CSV hosted on GitHub via `d3.csv`, with numeric conversion applied before rendering.
