Create beautiful SVG maps in react with d3-geo and topojson using a declarative api.

Read the docs, or check out the examples.


React-simple-maps aims to make working with svg maps in react easier. It handles tasks such as panning, zooming and simple rendering optimization, and takes advantage of parts of d3-geo and topojson-client instead of relying on the entire d3 library.

Since react-simple-maps leaves DOM work to react, it can also easily be used with other libraries, such as react-spring and react-annotation.


To install react-simple-maps

$ npm install --save react-simple-maps@beta

…or if you use yarn:

$ yarn add react-simple-maps@beta


React-simple-maps exposes a set of components that can be combined to create svg maps with markers and annotations. In order to render a map you have to provide a reference to a valid topojson file. You can find example topojson files in the topojson-maps folder or on topojson world-atlas. To learn how to make your own topojson maps from shapefiles, please read “How to convert and prepare TopoJSON files for interactive mapping with d3” on medium.

import React from "react"
import ReactDOM from "react-dom"
import {
} from "react-simple-maps"

// url to a valid topojson file
const geoUrl =

const App = () => {
  return (
        <Geographies geography={geoUrl}>
          {({geographies}) => geographies.map(geo =>
            <Geography key={geo.rsmKey} geography={geo} />

document.addEventListener("DOMContentLoaded", () => {
  ReactDOM.render(<App />, document.getElementById("app"))

Check out the live example

The above will render a world map using the equal earth projection. You can read more about this projection on Shaded Relief and on Wikipedia.

For other examples and components, check out the documentation.
