This example displays US states grouped into four census regions—Northeast, Midwest, South, and West—each filled with a distinct color. It uses d3.json to load the TopoJSON file, topojson.merge to combine state geometries by region, and d3.geoPath to render the resulting shapes as SVG paths. State groupings are defined using d3.set of FIPS codes, and CSS classes control the fill colors.

Fixed projection for US States

This example divides US states into four color-coded census regions—Northeast, Midwest, South, and West—drawn as fixed geographic projections. It uses D3 v5 with `d3.json`, `d3.geoPath`, and the `topojson` library to merge state geometries from the us-10m.v1 TopoJSON dataset. Each region is rendered as a separate SVG path with distinct fill colors defined in CSS.

Fixed projection for US States

This example displays a choropleth map of the United States, with states grouped into four color-coded regions: Northeast, Midwest, South, and West. It uses `d3.json` to load US TopoJSON data from `us-10m.v1.json`, then `topojson.feature` and `topojson.merge` to extract and combine state geometries by region. The paths are rendered as SVG elements using `d3.geoPath`, with regions filtered by state FIPS codes.

Fixed projection for US States

This example displays the contiguous United States color-coded by Census region: the Northeast, Midwest, South, and West. Each regional group of states is drawn as a separate path element, with the colors defined in CSS. The visualization uses the D3 library’s `geoPath` to render geographic data and the TopoJSON `feature` and `merge` functions to combine the US states dataset with its geometries. The map is rendered as an SVG, and the data is loaded from the `us-10m.v1.json` file.

Fixed projection for US States

This map visualization uses a fixed projection to display the four major U.S. census regions—Northeast, Midwest, South, and West—as distinct colored areas. It renders US state boundaries from the `us-10m` TopoJSON dataset, merging state geometries by regional ID using the `topojson` `merge` function. The D3 `select` and `geoPath` APIs generate SVG paths for each region, with styles defined in a stylesheet assigning each region a unique fill color.

Fixed projection for US States

This example renders a fixed-projection map of US states using d3.geoPath and TopoJSON data from us-10m.v1.json. It displays all state boundaries in gray with black strokes, highlighting 27 selected states in yellow based on a predefined set of FIPS IDs. The visualization demonstrates how to load and convert TopoJSON features with the topojson.feature API, then bind them to SVG path elements. The projection is left null, producing raw geographic coordinates without any transformation.

Fixed projection for US States

This example visualizes US states colored by region, using sales data from an avocado dataset filtered to a single date. The map renders geographic boundaries and circles representing data points through an SVG. It processes TopoJSON and CSV data with `d3.json` and `d3.csv`, merges them via `topojson.feature`, and applies static regional color fills for the Northeast, Midwest, South, and West. The `d3.geoPath` API generates the state outlines, while CSS classes define each region’s fill color.

Fixed projection for US States

This example displays a fixed projection of US states using d3.geoAlbersUsa and d3.geoPath, with red circles marking the geographic centroid of each state. It loads avocado sales data from a CSV and merges it with TopoJSON state boundaries using topojson.feature. The visualization renders state shapes as SVG paths, with color-coded regional groupings (Northeast, Midwest, South, West) defined via d3.set filters, though the primary rendering shows all states in green with red centroid markers. The code uses d3.csv, d3.json, and d3.geoCentroid to process and position the data.

Fixed projection for US States

This example displays a choropleth map of US states using D3 v5 and the TopoJSON us-10m dataset, where each state is drawn as an SVG path with d3.geoPath. The map is projected using d3.geoAlbersUsa. Avocado sales data from a CSV file (specifically for January 15, 2017) is joined to state features. Red circles are placed at each state’s centroid (via d3.geoCentroid) to indicate data points, while CSS classes define region-specific fill colors for the Northeast, Midwest, South, and West, although region merging is commented out.
