My USA Map

USA Map

This example displays a map of the United States, rendered as an SVG using a React component. It shows the nation’s land area in green, state boundaries as black lines, and an orange sphere background. The code employs D3’s `geoAlbers` projection and `geoPath` to draw geographic features, with `geoGraticule` available for reference lines. TopoJSON data from the `us-atlas` repository is loaded via `d3.json`, and the `feature` and `mesh` functions extract the landmass and state interiors.

USA Country Map

This example renders a choropleth-style USA map using SVG, showing state boundaries and filled land areas in orange. It uses D3’s `geoPath` and the `geo-albers-usa-territories` projection, with React managing the component structure. TopoJSON data is loaded via `d3.json`, and state outlines are drawn using `feature` and `mesh` from the `topojson` library. The map highlights territorial inclusion through the custom projection, while the `styles.css` defines the land fill and interior stroke.

country map

This example displays a map of the United States with state boundaries, rendered as SVG paths using D3’s `geoAlbers` projection and `geoPath`. It shows land areas in blue, a graticule sphere in purple, and state interiors highlighted with yellow strokes. The map loads US Atlas TopoJSON data from jsdelivr, processes it with `topojson.feature` and `topojson.mesh`, and is built within a React component using the `geoGraticule` API to draw the graticule lines.

United States of America Map

This example displays an interactive map of the United States derived from US Atlas topoJSON data. Using the `geoAlbersUsa` projection and `geoPath` API, it renders state boundaries as SVG paths with a tan fill over a blue ocean backdrop. React manages the component structure, while D3’s `json` method loads the topology and the topojson library converts it to GeoJSON. Hovering highlights states with a dark green color, showcasing basic spatial rendering with React and D3 integration.

USA Country Map

This example displays a choropleth-style map of the United States, showing state boundaries and land areas in light green with black interior borders. It uses React to render an SVG, with D3's `geoPath` and the `geoAlbersUsaTerritories` projection from the `geo-albers-usa-territories` library. TopoJSON data is loaded from a remote URL, and the `feature` and `mesh` APIs extract land and interior boundaries for drawing. The visualization focuses on geographic shape rather than additional quantitative data.

US_Map

A choropleth-style map displays the contiguous United States with state boundaries, rendered in SVG using React. The visualization uses `d3.geoAlbers` for projection and `d3.geoPath` to draw geographic features, with `d3.geoGraticule` generating graticule lines. Land areas are filled pink, interiors stroked darkblue, and the sphere background is yellow, styled via CSS. Geographic data comes from the US Atlas TopoJSON, processed with `topojson.feature` and `topojson.mesh`.

Country map

This example shows a map of the United States with its individual states rendered as sky-blue filled regions and their shared borders drawn as teal lines. It uses the `geoAlbersUsaTerritories` projection and `d3.geoPath` to convert TopoJSON data from the `us-atlas` package into SVG paths. The React component `Marks` maps over the land features and renders the interiors with a mesh, while a graticule is generated but not displayed. Data is loaded asynchronously via `d3.json` and processed with TopoJSON’s `feature` and `mesh` functions.

usmap

This example displays a choropleth-style map of the United States, drawn as gray state boundaries on a dark background. It uses the geoAlbersUsa projection to render the states as SVG paths, with the geographic data loaded from the us-atlas TopoJSON file. The React component fetches the data via useData, converts TopoJSON to GeoJSON with the feature function from topojson, and passes it to Marks, which generates the paths using d3.geoPath.
