Forked from ThemeRiver of the House Property Sales

This visualization uses a streamgraph to display median house sale prices over time, broken down by property type and number of bedrooms. A dropdown menu allows the user to select which stream is sorted at the top of the graph. The stacked areas are rendered as SVG paths using `d3.area` with a `stackOffsetSilhouette` layout, and the x-axis encodes time as years with seasonal divisions. Hovering over a stream reveals a tooltip with the price for that date, calculated from the stack’s bounds. The data comes from a CSV file (`ma_lga_12345.csv`) listing sale dates and median prices.

HW6

This visualization shows a ThemeRiver of house property sales in a specific area from 2007 to 2019, with each colored stream representing homes with two, three, four, or five bedrooms. The height of each stream reflects the median sale price (in dollars) for that property type quarterly. The code uses d3.stack with stackOffsetWiggle to create the flowing river layout, d3.area to draw the paths, and d3.scaleTime, d3.scaleLinear, and d3.scaleOrdinal for axes and coloring. An interactive tooltip, styled via CSS, reveals the exact price and season when hovering over any stream.

Homework 6

This interactive ThemeRiver chart visualizes median house prices over time, segmented by property type and bedroom count, using data from `ma_lga.csv`. The stacked streamgraph renders as SVG paths generated with `d3.area()` and `d3.curveBasis`, with colors from `d3.scaleOrdinal(d3.schemeTableau10)`. Users can click side labels to hide streams, hover to display a tooltip with date and price via `d3.pointer`, and click two streams to swap their stacking order, triggering an animated re-render with `d3.flatGroup` and `d3.minIndex`.

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.

A theme river displays the moving average of house property sales prices over time, broken down by property type and bedroom count. The visualization uses a silhouette offset to stack the series symmetrically around a central axis, highlighting each category's contribution. Users can drag and drop colored blocks to reorder the legend, which triggers an immediate redraw of the stacked areas via `d3.stack` and `d3.area`. The chart is built with `d3.csv`, `moment.js` for date parsing, and SortableJS for interactive reordering.

This interactive streamgraph visualizes quarterly median sale prices for houses and units with varying bedroom counts, sourced from the data.csv file. Users can reorder the legend categories through drag-and-drop, which triggers a redrawing of the stacked time-series chart via the `render` function. The visualization uses D3.js v6 for creating the SVG, scaling axes, and rendering the tooltip, while Sortable.js handles the reordering. The y-axis is fixed between -4,000,000 and 4,000,000 to accommodate the stacked values.

A streamgraph visualizes quarterly median sale prices for houses with two to five bedrooms in King County, Washington, from 2007 to 2019. The chart uses a silhouette offset to center the flowing areas around a shared baseline, with color encoding by bedroom count. Hovering over a time segment highlights the exact sale price and property type via a tooltip. The visualization is built with D3.js, using `d3.stack` with `stackOffsetSilhouette`, `d3.area` with curveBasis, and `d3.schemeTableau10` for categorical coloring. Data comes from a CSV file of median sale values.

Untitled

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.

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.
