import React from "react";
import ReactImageAnnotate from "react-image-annotate";

const App = () => (
  <ReactImageAnnotate
    labelImages
    regionClsList={["Alpha", "Beta", "Charlie", "Delta"]}
    regionTagList={["tag1", "tag2", "tag3"]}
    images={[
      {
        src: "https://placekitten.com/408/287",
        name: "Image 1",
        regions: []
      }
    ]}

export default App;

To get the proper fonts, make sure to import the Inter UI or Roboto font, the following line added to a css file should suffice.

@import url("https://rsms.me/inter/inter.css");
