A scatter plot displays the relationship between ground living area in square feet and sale price for individual properties. Each black circle represents a home, with position encoding both variables along linear axes. The visualization uses D3 v4’s `scaleLinear`, `axisBottom`, and `axisLeft` to render the chart in SVG within a React framework. Data loads from an external CSV file via `d3.csv`, plotting 1.5-pixel-radius circles without additional encoding.
