This example renders a natural Earth projection map with graticules, country borders, and shaded landmasses using SVG. It loads world atlas TopoJSON data via `d3.json` and topojson’s `feature` and `mesh` functions, then draws paths with `d3.geoPath`. The map displays city points from a CSV dataset loaded with `d3.csv`, converted to numeric coordinates, though the points themselves are not yet drawn. React manages loading states for both datasets through custom hooks.

AI-generated description

A program that loads in some data about CSS named colors using D3 utilities, and uses React state to render the data.

Points on a Map

This example displays a world map with points marking cities, rendered as an SVG using D3’s geoNaturalEarth1 projection and geoPath. The map shows landmasses, graticules, and country borders from the world-atlas TopoJSON, while city locations from a CSV file are plotted as semi-transparent circles. React manages the component state, fetching the data with useWorldAtlas and useCities hooks, and the d3.geoPath calculates the projected coordinates for each circle.

Point on a Map

This example displays a world map with country boundaries and graticules, rendered using an SVG projection. The visualization uses `d3.geoNaturalEarth1` and `d3.geoPath` to draw landmasses and interior borders from World Atlas TopoJSON data, with a styled sphere and graticule overlay. React manages the component hierarchy, while `d3.json` loads the topology and `topojson.feature` and `topojson.mesh` extract the geographic features. The map presents a clean, polished cartographic style with distinct colors for land, borders, and graticules.

Points on a Map

This example displays a natural Earth projection map with country boundaries, graticules, and city points overlaid as semi-transparent teal circles. The visualization uses d3.geoNaturalEarth1 and d3.geoPath to render landmasses and interior borders from World Atlas TopoJSON data, while a CSV of world cities is mapped through the projection to position each dot. The React component structure manages asynchronous data loading via useWorldAtlas and useCities hooks, with SVG rendering styled through CSS to create a clean, polished aesthetic.

Points on a map

This example displays a natural Earth projection world map with city locations plotted as semi-transparent teal circles. It loads world geography from the World Atlas TopoJSON and city coordinates from a CSV file. Using React hooks, it fetches both datasets and renders them as SVG elements. The map includes graticules, country boundaries, and interior borders, with cities positioned via the `d3.geoNaturalEarth1` projection and `d3.geoPath`. The visualization is built with D3 v6, React, and uses `d3.geoGraticule` for the background grid.

Points on a Map - React, D3

This example displays a world map with city points, using a natural Earth projection to render country boundaries, graticules, and interior borders from World Atlas TopoJSON data. City locations are plotted as semi-transparent circles based on latitude and longitude coordinates loaded from a CSV file. The visualization is built with React for component structure and D3 v5’s `geoNaturalEarth1`, `geoPath`, and `geoGraticule` for map geometry, rendered as SVG elements.

Points on a map

This example projects the world’s countries as SVG paths onto a Natural Earth projection using the `geoNaturalEarth1` projection and `geoPath` from D3 v7. It displays graticules and sphere outlines alongside landmasses, with a topological mesh of country borders drawn from the `world-atlas` dataset. The React app fetches TopoJSON, converts it to GeoJSON via `topojson.feature` and `topojson.mesh`, and styles the resulting shapes with CSS.

Points on a Map

A world map displays country boundaries and graticules, with hundreds of semi-transparent points marking city locations. The visualization uses D3’s `geoNaturalEarth1` projection and `geoPath` to render landmasses and interiors from World Atlas Topojson, while city coordinates are projected and drawn as SVG circles. React manages the component state, fetching data via `useEffect` and D3’s `csv` and `json` loaders.

points on a Map

This example displays a world map with semi-transparent points representing cities, overlaid on a natural Earth projection. The visualization uses D3 v5’s `geoNaturalEarth1` and `geoPath` to render the sphere, graticules, landmasses, and country interiors from a TopoJSON world atlas, while city coordinates from a CSV are projected and drawn as circles. React manages the component state, fetching data asynchronously with `useEffect` and rendering the SVG marks via a custom `Marks` component.
