This visualization shows quarterly median property prices for houses with 2 to 5 bedrooms from 2007 to 2019, using a stacked area chart to compare price trends across these groups. The chart uses D3 v6’s `csv` loader to fetch data from an external URL, `scaleLinear` for the axes, and `stack` with `stackOffsetSilhouette` for layering, though the offset is commented out. Each bedroom category is rendered as a distinct SVG path via `d3.area`, with an ordinal color scale distinguishing the series. The y-axis displays a fixed range of -100,000 to 100,000, and the x-axis uses five ticks for readability.
