This example visualizes house prices over time using a line chart with a filled area beneath the curve, rendered as SVG in a React-based VizHub project. The chart uses D3 v5 APIs including `scaleTime`, `scaleLinear`, `line`, `area`, and `curveBasis` to draw the smoothed trend, with axes from `axisBottom` and `axisLeft`. Data is loaded via `csv` from a remote GitHub Gist, parsed into `Date` and numeric cost values, and styled with CSS classes for bold black lines and a blue fill.
