This example displays a choropleth map of the United States using GeoJSON data from a gist, with each state’s population from 2010 encoded by color. It uses d3-geo’s `d3.geoPath` to render the state boundaries and fill them with a color scale based on the `POP2010` property. The map is drawn with SVG, and the layout is generated by projecting the geographic coordinates. The rendering demonstrates how spatial data can be visually encoded using standard D3.js geographic utilities.

This example displays a choropleth-style map of the United States, rendering each state as a separate SVG path. The visualization shows the geographic boundaries of all states by loading GeoJSON data from a remote gist. Using D3 v3, the code applies `d3.geo.path()` to convert GeoJSON features into SVG path data, then appends each path to an SVG container with a red border. The map is static, with no interactivity or color encoding, serving as a basic demonstration of D3's geographic projection capabilities.

colored-data.geojson

A choropleth-style map displays a small set of U.S. counties colored with a categorical palette. The visualization loads a GeoJSON FeatureCollection, where each county polygon includes a `fill` property defining its color. The code uses `d3.geoPath` to project and render the geographic shapes as SVG paths, assigning each county its designated fill color. It relies on the D3 library to handle the GeoJSON parsing and path generation.

Gist c74a36a544e6649522366453f5e1d6fa

A choropleth-style map of the United States renders state boundaries as black outlines on a white background, using an Albers USA projection centered within a 700x580 SVG. The visualization loads geographic features from a local `us-states.json` file and draws each state path via D3 v4’s `d3.geoPath` with a `d3.geoAlbersUsa` projection. No data values or color encoding are applied, leaving the map purely as a geometric outline of the country’s administrative divisions.

USA Map

This example displays a choropleth map of the United States, coloring each state according to a value from a local CSV file. The code loads GeoJSON geographic data and uses `d3.geoPath` for map rendering, while a linear color scale maps data values to a light-to-dark blue gradient. The map uses SVG paths with white strokes, and states without corresponding data appear gray. It demonstrates loading external data via `d3.csv` and `d3.json`.

Choropleth population map

A choropleth map of the United States displays state-level population counts from 1990, using a color gradient from light orange to dark red. The map is rendered as SVG with D3 v3, leveraging `d3.geo.path` and TopoJSON for state boundaries. Population data from a CSV file is joined to state IDs, and a custom `d3.scale.quantize` interpolates colors across 100 steps. Hovering over a state triggers a tooltip and animates opacity, while the legend and interactivity are built with jQuery and D3 transitions.

USA Country Map with Topojson data

This example displays a choropleth-style map of the United States, with each state rendered as a separate SVG path using a topojson dataset. It shows state boundaries and names via tooltips. The code uses D3 v5’s `geoAlbersUsa` projection and `geoPath` to generate the paths, while `topojson.feature` converts the TopoJSON topology into GeoJSON features. The map is drawn with SVG elements, and the data is loaded asynchronously from a GitHub gist using D3’s `json` method.

Gist 08d3bc545278d6a3b2d22df875392612

This example visualizes U.S. state boundaries using D3 v4’s geoAlbersUsa projection and d3.geoPath to render geographic features from a local us-states.json file. The SVG canvas, sized 700x580, is appended to the body, and each state’s polygon is drawn as a path element with a default fill and stroke. The map is centered using a translate of [width/2, height/2], and the simple code demonstrates how to load and project GeoJSON data for display. No interactions or styling are applied, keeping the focus on the map layout.

US Choropleths Map And Captital/Major Cities

This example displays a choropleth map of the contiguous United States with state boundaries rendered as colored polygons, overlaid with two city datasets. State colors transition from white to blue via a `scaleLinear` color scale, while graticules and interior borders are drawn using `d3.geoPath` and `d3.geoGraticule`. Population data from a world cities CSV appears as semi-transparent purple circles sized with `scaleSqrt`, and state capitals from a Vega JSON file are fixed black dots. The map uses TopoJSON from the us-atlas library, projected with `geoAlbers` in an SVG rendered through React.
