This scatter plot visualizes King County house sales, showing the relationship between price and square footage with points colored to distinguish waterfront properties from non-waterfront ones. The visualization renders as an SVG using D3 v6, employing `scaleLinear` for the x and y axes, `scaleOrdinal` for categorical color encoding, and `d3.axisLeft` and `d3.axisBottom` for labeled axes. A custom legend explains the color mapping, while the data is loaded and processed through D3's selection and data-join methods.
