### Rendering a Basic World Map in React

Source: https://github.com/zcreativelabs/react-simple-maps/blob/main/README.md

This snippet demonstrates how to render a basic world map using `react-simple-maps` components. It imports necessary components, defines a URL to a topojson file, and uses `ComposableMap`, `Geographies`, and `Geography` to display the map. This example requires `react` and `react-dom` to be installed.

```jsx
import React from "react";
import ReactDOM from "react-dom";
import { ComposableMap, Geographies, Geography } from "react-simple-maps";

// url to a valid topojson file
const geoUrl =
  "https://raw.githubusercontent.com/deldersveld/topojson/master/world-countries.json";

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

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