A choropleth map of U.S. county education levels, rendered as SVG paths with an Albers USA projection, displays a visual distribution of data across the country. The React app loads county boundary TopoJSON and education statistics via `d3.json`, then uses `d3.geoPath` with `geoAlbersUsa()` to project each county boundary. While the code defines the map’s layout and data fetching, the actual color encoding for each county’s education value is not implemented, leaving the map uncolored. The visualization depends on React state to coordinate asynchronous loading of both datasets before rendering.

USA Education Choropleth Map (fcc project)

This choropleth map shows the percentage of adults with a bachelor’s degree or higher across U.S. counties, using a sequential YlGn color scale. The React app loads county, state, and nation boundaries from a TopoJSON file and education data from freeCodeCamp’s CDN, then renders them as SVG paths via `d3.geoPath`. County colors are assigned by looking up each county’s FIPS code in a Map, with white fill for missing data. State outlines are drawn as a mesh overlay, and the map is generated with `d3.json`, `topojson.feature`, and `scaleSequential`.

Let's make a map with D3.js!

This example demonstrates how to create a choropleth map of U.S. counties using D3.js. It renders an SVG projection of the United States with a light background, then overlays county boundaries and merges them with education data loaded from freeCodeCamp’s testable projects API. The code uses `d3.geoAlbersUsa` for the projection, `d3.geoPath` to generate paths, and TopoJSON’s `feature` method to extract county geometries. Education statistics are fetched in parallel with county boundaries via `Promise.all`. The resulting visualization shows county outlines but does not yet color them by data values.

Untitled

This choropleth map displays U.S. county-level education data, with each county drawn as a filled path whose color would encode the associated metric. The visualization loads county boundaries from a TopoJSON file and joins them with a separate JSON dataset containing education statistics. Using d3.geoPath, the code renders the geographic features into an SVG canvas, while d3.json is used to fetch both data sources sequentially, ensuring the map draws only after all data arrives.

test

This choropleth map shades US counties according to the percentage of residents with a bachelor's degree or higher, using an orange-yellow sequential color scale. The visualization leverages React for the SVG rendering, with D3's `geoPath` for drawing county, state, and nation boundaries from a TopoJSON source. Education data is fetched from a freeCodeCamp-hosted JSON file, and county colors are mapped via D3's `scaleSequential` and `interpolateYlOrRd`.

Fork of USA Education Choropleth Map (fcc project)

This fork of the freeCodeCamp choropleth map example visualizes the percentage of adults with a bachelor’s degree or higher across U.S. counties, using a sequential yellow-green color scale. The map renders as SVG via React, with county boundaries drawn using d3.geoPath and topojson feature extraction from county, state, and nation geometries. County color values are mapped through a d3.scaleSequential with interpolateYlGn, while education data is loaded from the freeCodeCamp JSON endpoint and joined to county IDs.

map: usa, counties

This example renders a choropleth-style map of the United States, displaying county and state boundaries overlaid on landmasses, with graticules and a sphere outline. It uses a React component with `d3.geoAlbersUsa` for projection and `d3.geoPath` for drawing geometries. Data comes from the US Atlas TopoJSON (`us-atlas@3.0.0/counties-10m.json`), processed with `topojson.feature` and `topojson.mesh`. Interactive tooltips show county and state names on hover. The SVG output is styled with semi-transparent fills and distinctive boundary strokes.

map

This example displays a map of U.S. counties as unfilled, stroked polygons on a blank background, all rendered as SVG paths. The map shows the geographic boundaries without additional fill or data encoding. The code uses React with D3 v5 functions including `d3.geoAlbersUsa` for the projection, `d3.geoPath` to generate the path data, and TopoJSON's `feature` function to convert topojson data into GeoJSON features. Data loads asynchronously via `d3.json` from a remote URL, and each feature is mapped to an SVG `<path>` element with a thin teal stroke.

Fork of Assignment 9: Choropleth Map

This choropleth map displays the percentage of adults with a bachelor’s degree or higher per U.S. county using a blue threshold color scale and a legend with tick marks. The code loads education data from a CSV and U.S. county boundaries from TopoJSON via `d3.json` and `d3.csv`, then renders paths with `d3.geoPath`. It uses `d3.scaleThreshold` and `d3.schemeBlues` for coloring, adds hover tooltips via SVG `<title>` elements, and overlays state boundaries with `topojson.mesh`. The visualization is built with D3 v5 and React, drawing to an SVG canvas.
