This area chart visualizes the Boston housing dataset, showing the relationship between the average number of rooms (RM) and the median home value (MEDV) in thousands of dollars. The chart uses a steelblue filled area to depict the trend, with the data sorted by room count. Built with D3 v5, the visualization employs `scaleLinear`, `area`, `axisBottom`, and `axisLeft` to render the SVG. Data is loaded asynchronously via `csv` from a GitHub repository, and axes and a legend are added manually within the SVG container.
