This visualization displays the median sale price of houses over time, segmented by the number of bedrooms. The chart uses a silhouette-style stacked area chart to show price trends for each category. The data is loaded from a remote CSV file using the `d3.csv` function, and the `MA` values are parsed as numbers. The visualization uses `d3.scalePoint` for the x-axis and `d3.scaleLinear` for the y-axis, with `d3.group` to nest the data by date. The chart is rendered as an SVG using `d3.area` paths.

hw6_me

This visualization shows a ThemeRiver chart tracking median house sale prices over time, segmented by property type and bedroom count. Seven categories—ranging from two-bedroom houses to three-bedroom units—are displayed as colored streams that flow and stack vertically. The chart uses D3 v6 with `d3.stack` and `stackOffsetSilhouette` to create the silhouette layout, while `d3.scalePoint` and `d3.area` handle the temporal axis and stream paths. Data comes from a CSV file containing quarterly sale prices, with each category assigned a distinct color from a ordinal scale.

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.

A ThemeRiver visualization displays changes in Massachusetts home sale prices over time, stacked into flowing streams by bedroom count. The chart uses D3 v6 to load CSV data, transforms it via the `d3.stack` generator, and renders smooth SVG areas with `d3.area` and `curveBasis`. Time and price scales map dates to the x-axis and cumulative price ranges to the y-axis, while each stream is colored by housing category.

Untitled

This example shows a stacked area chart of house and unit sales over time, with the MA (moving average) values across seven property types. The chart uses a silhouette offset, centering the data around zero. A list on the side enables the user to reorder the stacking sequence, and the chart redraws accordingly. It is built with D3.js, using `d3.stack`, `d3.area`, `d3.scaleTime`, and `d3.scaleOrdinal`. The data comes from a CSV file loaded via `d3.csv`, and hover interactions highlight individual areas with a tooltip.
